HIV drug resistance, viral suppression, and survival in children living with HIV in Brazil.

INTRODUCTION: Mutations associated with HIV drug resistance (DR) affect clinical outcomes. Understanding the prevalence of HIV DR and its association with viral suppression and survival in the paediatric population is key to inform patient care and health policies. METHODS: We used Brazilian monitoring systems to identify genotyping tests performed in children living with HIV aged ≤18 months between 2009 and 2020. We categorized HIV DR using three criteria: any HIV DR (R1), DR to nevirapine or efavirenz (R2), and DR to at least one antiretroviral recommended for children with HIV in Brazilian guidelines (R3). We investigated factors associated with HIV DR, viral suppression, and survival up to 3 years old using multivariable models. Lastly, we describe the annual prevalence of each type of HIV DR in Brazilian children with HIV between 2009 and 2020. RESULTS: We included 1152 children with HIV with a median age of 5 months at genotype testing; 57% were females. R1 was observed in 30%, R2 in 17%, and R3 in 21%. Children with HIV whose birth parents were exposed to nevirapine or efavirenz before delivery had higher odds of R2 (odds ratio 3.4; 95% confidence interval [CI] 1.1-10.8). Children with HIV with R1 or R3 had higher rates of death than those with HIV with no HIV DR in the adjusted models (adjusted hazard ratios 4.7 [95% CI 1.6-13.9] and 4.1 [95% CI 1.4-12.4], respectively). The prevalence of resistance to nevirapine and efavirenz peaked in 2015. Over time, the prevalence of genotyping tests with no detected resistance varied between 57% and 87%. CONCLUSION: HIV DR is highly prevalent in children with HIV and is associated with lower survival.

Illicit Fentanyl Use and Hepatitis C Virus Seroconversion Among People Who Inject Drugs in Tijuana and San Diego: Results From a Binational Cohort Study.

BACKGROUND: Illicitly manufactured fentanyl (IMF) increases overdose mortality, but its role in infectious disease transmission is unknown. We examined whether IMF use predicts hepatitis C virus (HCV) and human immunodeficiency virus (HIV) incidence among a cohort of people who inject drugs (PWID) in San Diego, California and Tijuana, Mexico. METHODS: PWID were recruited during 2020-2022, undergoing semi-annual interviewer-administered surveys and HIV and HCV serological rapid tests through 2024. Cox regression was conducted to examine predictors of seroconversion considering self-reported IMF use as a 6-month lagged, time-dependent covariate. RESULTS: Of 398 PWID at baseline, 67% resided in San Diego, 70% were male, median age was 43 years, 42% reported receptive needle sharing, and 25% reported using IMF. HCV incidence was 14.26 per 100 person-years (95% confidence interval [CI]: 11.49-17.02), and HIV incidence was 1.29 (95% CI: .49-2.10). IMF was associated with HCV seroconversion, with a univariable hazard ratio (HR) of 1.64 (95% CI: 1.09-2.40), and multivariable HR of 1.57 (95% CI: 1.03-2.40). The direction of the relationship with HIV was similar, albeit not significant (HR 2.39; 95% CI: .66-8.64). CONCLUSIONS: We document a novel association between IMF and HCV seroconversion among PWID in Tijuana-San Diego. Few HIV seroconversions (n = 10) precluded our ability to assess if a similar relationship held for HIV. IMF's short half-life may destabilize PWID-increasing the need for repeat dosing and sharing smoking materials and syringes. New preventive care approaches may reduce HCV transmission in the fentanyl era.

Epidemiological profile of individuals with HIV/Aids in a municipality in Maranhão State, Brazil, from 2017 to 2020 / Perfil epidemiológico de individuos con VIH/SIDA en municipio en Maranhão, Brasil, de 2017 a 2020 / Perfil epidemiológico de indivíduos com HIV/Aids em município no Maranhão, Brasil, de 2017 a 2020

Background and Objective: To understand the main forms of transmission of HIV in order to foster the containment of the transmission chain, early diagnosis and the epidemiological profile of patients. In this sense, it will enable the analysis of the epidemiological profile and the transmissibility variables of patients with HIV/Aids from the municipality of Imperatriz-MA.. Method: This is an observational cross-sectional study. Data collection was performed from the analysis of patients' records registered in the Center for Testing and Counseling (CTA) from 2017 to 2020. For data collection, a questionnaire with transmission variables and epidemiological characteristics of patients was used. Results: From January 2017 to December 2020, 211 medical records were filed. Of these, 71.6% were male, 55.5% of the participants were between 21 and 40 years, and 66.4% from Imperatriz-MA. The most prevalent type of exposure was sexual intercourse without a condom. Among the participants, 83.9% (n=177) were positive only for HIV. About 140 people with HIV had an undetectable viral load (VL) (< 50 copies/ml) after 6 months of using antiretroviral therapy, making it low transmissibility. Conclusion: The study was able to characterize the epidemiological profile of patients from the Specialized Assistance Service (SAE) in Imperatriz between 2017 and 2020. Despite the increase in the number of cases among women, the most affected public remains young men, from 21 to 40 years of age, with 8 to 11 years of education, single and brown. Sexual intercourse without a condom is the main type of exposure.(AU)

Clinical aspects of co-infection by HIV and syphilis in pregnancy and exposure in newborn intended at Pediatric Hospital of Santa Catarina / Aspectos clínicos da coinfecção por HIV e sífilis na gestação e da exposição de recém-nascidos atendidos em Hospital Pediátrico de Santa Catarina

Introduction: Sexually transmitted infections frequently affect pregnant women and, consequently, newborns. HIV and syphilis are vertically transmitted to children and co-infection requires special attention due to its clinical implications. Objective: To describe clinical aspects of HIV/syphilis coinfection during pregnancy and the exposure of newborns to infections treated at a pediatric reference hospital in Santa Catarina between 2015 and 2020. Methods: Observational, descriptive study, secondary to a line of research "Epidemiological description of children exposed to HIV" from January 2015 to December 2020 in a tertiary pediatric hospital in Santa Catarina. Results: 678 medical records were analyzed with ICD Z.206 (contact with and exposure to HIV), in which 71 (10.5%) newborns were exposed to HIV and Syphilis co-infection. Of these, 37 (52.1%) were male, 14 (19.7%) confirmed a diagnosis of HIV and 30 (42.2%) of congenital syphilis. Of the co-infected pregnant women, 38 (53.5%) were diagnosed with HIV prior to pregnancy, 53 (74.6%) used ART and 40 (52.1%) used harmful substances. Furthermore, 34 (46.4%) pregnant women had a minimum number of 6 prenatal consultations, 35 (49.3%) had vaginal births and 29 (40.8%) had undetectable HIV RNA quantification at the time of delivery. HIV prophylaxis for newborns occurred in 66 (92.9%) of cases. Conclusion: It is concluded that the studied population was mostly made up of pregnant women who were diagnosed with HIV infection prior to pregnancy. Of these, the majority were using ART, but the minority carried out the minimum number of consultations recommended by the Ministry of Health. Regarding newborns, the majority received HIV prophylaxis. (AU)

Introdução: As infecções sexualmente transmissíveis afetam frequentemente gestantes e, consequentemente, os recém-nascidos (RN). O vírus da imunodeficiência humana (HIV) e a sífilis são transmitidos verticalmente para as crianças e a coinfecção requer atenção especial por suas implicações clínicas. Objetivo: Descrever aspectos clínicos da coinfecção HIV/sífilis na gestação e da exposição de RN às infecções atendidos em um hospital de referência pediátrica em Santa Catarina entre 2015 e 2020. Métodos: Estudo observacional, descritivo, secundário à linha de pesquisa "Descrição epidemiológica de crianças expostas ao HIV" no período de janeiro de 2015 a dezembro de 2020, em um hospital pediátrico terciário de Santa Catarina. Resultados: Foram analisados 678 prontuários com Classificação Internacional de Doenças ­ CID Z.206 (contato com e exposição ao HIV), nos quais 71 (10,5%) RN foram expostos à coinfecção HIV e sífilis. Destes, 37 (52,1%) eram do sexo masculino, 14 (19,7%) confirmaram diagnóstico de HIV e 30 (42,2%) de sífilis congênita. Das gestantes coinfectadas, 38 (53,5%) possuíam diagnóstico do HIV prévio à gestação, 53 (74,6%) usaram terapia antirretroviral (TARV) e 40 (52,1%) utilizaram substâncias nocivas. Ainda, 34 (46,4%) gestantes obtiveram o número mínimo de seis consultas pré-natais, 35 (49,3%) realizaram partos vaginais e 29 (40,8%) possuíam quantificação RNA-HIV não detectável no momento do parto. A profilaxia para o HIV do RN ocorreu em 66 (92,9%) dos casos. Conclusão: Conclui-se que a população estudada foi formada, na sua maioria, por gestantes que receberam o diagnóstico de infecção pelo vírus do HIV prévio à gestação. Destas, a maioria estava em uso de TARV, porém a minoria realizou o número mínimo de consultas preconizadas pelo Ministério da Saúde. Com relação aos RN, a maioria recebeu profilaxia ao HIV. (AU)

MPOX, o que sabemos sobre propagação e controle: uma revisão integrativa / MPOX, what we know about propagation and control: an integrative review / Viruela del mono, qué sabemos sobre la propagación y el control: una revisión integradora

Esta é uma revisão integrativa que busca compreender os fatores associados à propagação e controle de mpox, seguindo as recomendações estabelecidas pela declaração Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A consulta foi feita nas bases de dados PubMed, Lilacs e Cochrane Library. Foram selecionados quinze artigos, com amostra majoritária de homens que fazem sexo sem proteção com homens e homens que viajaram para locais com surto da doença ou tiveram contato com pessoas infectadas. Os principais fatores associados à infecção e à propagação da doença foram históricos de viagem, sexo desprotegido, ingestão de carne possivelmente contaminada, aglomerados e contato próximo com pessoa sintomática. Quanto aos fatores relacionados à prevenção, estão principalmente associados à triagem de casos suspeitos, hábitos de higiene pessoal, uso de equipamentos de proteção individual e isolamento do doente.

This integrative review examines the factors associated with mpox spread and control, following the recommendations established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Bibliographic search was conducted on the PubMed, Lilacs and Cochrane Library databases. The final sample included 15 articles, mostly composed of men who have unprotected sex with men and men who traveled to places with a mpox outbreak or had contact with infected people. Travel history, unprotected sex, eating potentially contaminated meat, crowding and close contact with a symptomatic person were the main factors associated with mpox infection and spread. Prevention is mainly associated with the screening of suspected cases, personal hygiene habits, use of personal protective equipment and patient isolation.

Se seleccionaron quince artículos, con una muestra mayoritaria de hombres que tienen sexo con hombres sin protección y hombres que viajaron a lugares con brote de la enfermedad o que tuvieron contacto con personas infectadas. Los principales factores asociados con la infección y la propagación de la enfermedad fueron el historial de viajes, las relaciones sexuales sin protección, el consumo de carne potencialmente contaminada, el hacinamiento y el contacto cercano con una persona sintomática. Los factores relacionados con la prevención están asociados principalmente con el tamizaje de casos sospechosos, los hábitos de higiene personal, el uso de equipos de protección personal y el aislamiento del paciente.

Perceptions and feelings of pregnant women undergoing outpatient follow-up for toxoplasmosis

Introduction: Toxoplasmosis persists as a neglected disease and poses a challenge to public health, especially due to the risk of vertical transmission, which can lead to countless biological complications for the newborn and to psychological and emotional repercussions for the mother. Objective: To understand the perceptions and feelings of pregnant women affected by toxoplasmosis undergoing outpatient follow-up. Materials and Methods: A qualitative and exploratory study developed with 12 women with gestational toxoplasmosis undergoing specialized outpatient follow-up in a municipality from the state of Paraná, Brazil. The data were collected through semi-structured individual interviews and subjected to content analysis, supported by descending hierarchical classification. Results: The pregnant women experienced situations ranging from diagnosis and treatment to preventing the disease in the child and family. These experiences generated fear, distress and uncertainty about the disease, which were not adequately addressed during prenatal assistance in primary care. However, the pregnant women emphasized the importance of the multiprofessional team at the secondary level in monitoring and health education. Discussion: Although the pregnant women felt confident about the treatment and its implications for the child's health, discovering the diagnosis impacted their everyday lives and those of their families, especially due to lack of reliable information about toxoplasmosis and to the absence of emotional support at the primary level. Conclusions: There was a temporary scenario of disinformation among these women, who were not properly guided and supported. However, the guidelines offered in secondary health care were essential for improving knowledge and practices in health.

Oportunidades domiciliares para o desenvolvimento motor de lactentes verticalmente expostos ao HIV / Oportunidades domiciliarias para el desarrollo motor de lactantes expuestos a transmisión vertical del VIH / Home opportunities for the motor development of infants vertically exposed to HIV

Resumo Objetivo Avaliar as oportunidades do domicílio para o desenvolvimento motor de lactentes verticalmente expostos ao HIV de acordo com os níveis interdependentes do meio ambiente. Métodos Estudo transversal que incluiu familiares capazes de realizar sozinhos os cuidados cotidianos de lactentes expostos ao HIV com três a 18 meses de idade, em acompanhamento nos serviços de saúde em oito municípios no Sul do Brasil. Foram excluídos lactentes institucionalizados, com perda de seguimento ambulatorial ou impossibilidade de contato telefônico. Participaram do estudo 168 familiares mediante coleta de dados presencial e telefônica com caracterização do familiar, do lactente e do ambiente. Foram aplicadas as escalas de oportunidades no ambiente domiciliar para o desenvolvimento motor com a escala bebê e insegurança alimentar. Foram realizadas análises descritivas e correlações entre as variáveis independentes, seguidas de regressão de Poisson com variância robusta. Resultados As oportunidades totais do ambiente domiciliar foram classificadas como moderadamente adequadas (37,4%), variedade de estimulação excelente (35,4%), espaço físico moderadamente adequado (44,5%), brinquedos de motricidade grossa (38,0%) e de motricidade fina (38,7%) como menos que adequado. Houve associação para escolaridade (p < 0,005), renda (p < 0,013) e segurança alimentar (p < 0,032) com o desfecho menos que adequado ou moderadamente adequado para as oportunidades domiciliares. Conclusão Menores condições escolares, financeiras e de segurança alimentar implicam em menores oportunidades para o desenvolvimento motor, as quais podem ser potencializadas pela fragilidade clínica do lactente com uma condição sorológica ainda indefinida e pela demanda de cuidados habituais para prevenção da transmissão vertical.

Resumen Objetivo Evaluar las oportunidades del domicilio para el desarrollo motor de lactantes expuestos a transmisión vertical del VIH de acuerdo con los niveles interdependientes del medio ambiente. Métodos Estudio transversal en el que participaron familiares capaces de realizar solos los cuidados cotidianos de lactantes expuestos al VIH de tres a 18 meses de edad, atendidos en los servicios de salud de ocho municipios del sur de Brasil. Se excluyeron los lactantes institucionalizados, que perdieron el seguimiento ambulatorio o que no tenían posibilidad de contacto telefónico. Participaron en el estudio 168 familiares mediante recopilación de datos presencial y telefónica con caracterización familiar, del lactante y del ambiente. Se aplicaron las escalas de oportunidades del medio ambiente domiciliario para el desarrollo motor con la escala bebé e inseguridad alimentaria. Se realizaron análisis descriptivos y correlaciones entre las variables independientes, seguidas de regresión de Poisson con varianza robusta. Resultados Las oportunidades totales del ambiente domiciliario fueron clasificadas como moderadamente adecuadas (37,4 %), la variedad de estimulación fue excelente (35,4 %), el espacio físico moderadamente adecuado (44,5 %), los juguetes de motricidad gruesa (38,0 %) y de motricidad fina (38,7 %) como menos que adecuados. Hubo relación de escolaridad (p<0,005), ingresos (p<0,013) y seguridad alimentaria (p<0,032) con el resultado menos adecuado o moderadamente adecuado de oportunidades domiciliarias. Conclusión Menores condiciones escolares, financieras y de seguridad alimentaria conllevan menores oportunidades para el desarrollo motor, que pueden potencializarse por la fragilidad clínica del lactante con una condición serológica aún indefinida y por la demanda de cuidados habituales para la prevención de la transmisión vertical.

Abstract Objective to evaluate the opportunities of the home for the motor development of vertically exposed infants according to the interdependent levels of the environment. Methods This was a cross-sectional study which included family members who were capable of carrying out the daily care of HIV-exposed infants aged between three and 18 months who were being monitored by health services in eight municipalities in southern Brazil. Infants who were institutionalized, had lost their outpatient follow-up or were unable to be contacted by telephone were excluded. A total of 168 family members took part in the study through face-to-face and telephone data collection, characterizing the family member, the infant and the environment. The scales of opportunities in the home environment for motor development, the infant and food insecurity scales were applied. Descriptive analyses and correlations between the independent variables were carried out, followed by Poisson regression with robust variance. Results The total opportunities of the home environment were classified as moderately adequate (37.4%), variety of stimulation as excellent (35.4%), physical space as moderately adequate (44.5%), toys for gross motor skills (38.0%) and fine motor skills (38.7%) as less than adequate. There was an association for schooling (p < 0.005), income (p < 0.013) and food security (p < 0.032) with the outcome less than adequate or moderately adequate for home opportunities. Conclusion Poorer schooling, financial conditions and food security imply fewer opportunities for motor development, which can be exacerbated by the clinical fragility of infants with an as yet undefined serological condition and the demand for regular care to prevent vertical transmission.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.

Evaluating elimination of mother-to-child transmission of HIV in Suriname: a mixed method study.

Objectives: To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants. Methods: A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15-49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed. Results: In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6-215.3) and the child (OR 145.7, 95% CI 14.4-1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4-0.7) compared with urban living. Conclusions: HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

Mpox: Aspectos epidemiológicos, imunopatogênicos e manejo pré e pós-infecção / Mpox: Epidemiological, immunopathogenic aspects and pre- and post-infection management

Mpoxou Varíola M é uma zoonose causada por vírus do gênero Orthopoxvirus, causadores também da varíola comum. É uma doença considerada rara e autolimitada, sendo endêmica em países africanos. Entretanto, no ano de 2022 ganhou destaque devido ao surto global que se iniciou, quando o mundo ainda se recuperava da pandemia da COVID-19. Dessa forma, por se tratar de uma doença emergente, a presente revisão visa pontuar aspectos gerais do que se sabe até o momento sobre a Mpox, desde sua imunopatogenia até as formas atuais de prevenção e cuidados pós-infecção

Mpox or Variola M is a zoonosis caused by viruses of the genus Orthopoxvirus, which also cause smallpox. It is a disease considered rare and self-limiting, being endemic in African countries. However, in 2022, it gained prominence due to the global outbreak that began when the world was still recovering from the COVID-19 pandemic. Thus, as it is an emerging disease, this review aims to point out general aspects of what is known so far about Mpox, from its immunopathogenesis to current forms of prevention and post-infection care

Caracterização e geoespacialização da sífilis gestacional e congênita no Paraná, Brasil, 2012-2020 / Characterization and geospacialization of gestational and congenital syphilis in Paraná, Brazil, 2012-2020 / Caracterización y geoespacialización de sífilis gestacional y congénita en Paraná, Brasil, 2012-2020

A sífilis persiste como um problema de saúde pública, sobretudo pelos entraves existentes no enfrentamento da sífilis gestacional e congênita. Considerando que a ocorrência dessas infecções se relaciona a fatores maternos e programáticos, este estudo buscou analisar as características epidemiológicas do binômio mãe-filho exposto à sífilis e sua distribuição espacial no Paraná entre 2012 e 2020. Trata-se de estudo descritivo e ecológico, com dados dos sistemas nacionais de informação do Brasil. Foram considerados os casos de gestantes e de crianças registrados entre 2012 e 2020 no estado do Paraná. Foram apresentadas as frequências absolutas e relativas para a caracterização, calculando-se a variação percentual entre o primeiro e o último triênio. Ainda, foi empregado o índice de Moran para a geoespacialização segundo regiões de saúde. Houve predomínio em mulheres de 20 a 39 anos (71,24%), brancas (67,22%) e com até oito anos de estudo (80,76%), com diagnóstico nas fases primária e latente (76,42%). Os casos concentraram-se em crianças do sexo masculino (48,72%), diagnosticadas na fase recente (96,42%), e naquelas cujas mães aderiram ao pré-natal (88,88%), mas os parceiros, por sua vez, não foram tratados (69,46%). Houve aumento do diagnóstico materno durante o pré-natal (16,61%) e redução dos óbitos infantis por sífilis (31,25%). Observou-se concentração das notificações nas regiões Metropolitana e de Pato Branco. Em suma, as gestantes apresentaram idade reprodutiva e baixa escolaridade e foram tratadas durante o pré-natal, contudo, sem a inclusão dos parceiros. Ademais, evidenciou-se comportamento espacial aleatório nas regiões de saúde, com disparidade entre a sífilis gestacional e a congênita.

Syphilis remains as serious public health issue due to existing obstacles in combating gestational and congenital syphilis. Since the onset of these infections is related to maternal and programmatic factors, this study analyzed the epidemiological profile of the mother-child binomial exposed to syphilis and its spatial distribution in Paraná from 2012 to 2020. This is a descriptive, ecological study with data from Brazilian national information systems. Cases of pregnant women and children recorded between 2012 and 2020 in the state of Paraná were considered. Absolute and relative frequencies were estimated for characterization, calculating the percentage variation between the first and last three years. The Moran index was also used for geospacialization according to health regions. Most women were aged 20 to 39 years (71.24%), white (67.22%), and had up to 8 years of schooling (80.76%), with diagnosis in the primary and latent stages (76.42%). Most cases concerned male children (48.72%), diagnosed in the recent phase (96.42%), and from mothers who adhered to prenatal care (88.88%), but the partners were untreated (69.46%). Maternal diagnosis increased during prenatal care (16.61%) and infant deaths by syphilis decreased (31.25%). Most cases were notified in the Metropolitan and Pato Branco regions. In short, the pregnant women were of reproductive age, had low education, and were treated during prenatal care, but their partners were not included. The health regions showed random spatial behavior, with disparity between gestational and congenital syphilis.

La sífilis persiste como un problema de salud pública, principalmente por los obstáculos en hacer frente la sífilis gestacional y congénita. Teniendo en cuenta que la ocurrencia de estas infecciones está relacionada con los factores maternos y programáticos, este estudio tuvo como objetivo analizar las características epidemiológicas del binomio madre-hijo expuestos a la sífilis y la distribución espacial en Paraná (Brasil) entre 2012 y 2020. Se trata de un estudio descriptivo y ecológico, con datos de los sistemas de información nacionales de Brasil. Se consideraron los casos de mujeres embarazadas y niños registrados entre 2012 y 2020 en Paraná. Se presentaron las frecuencias absolutas y relativas, calculando la variación porcentual entre el primer y el último trienio. Asimismo, se utilizó el índice de Moran, según regiones de salud. Predominaron las mujeres de entre 20 y 39 años de edad (71,24%), blancas (67,22%), con hasta ocho años de estudio (80,76%), con diagnóstico en estadio primario y latente (76,42%). Los casos se concentraron en hijos varones (48,72%), diagnosticados en fase reciente (96,42%), y en aquellos cuyas madres tuvieron acceso a los cuidados prenatales (88,88%), pero su pareja no recibió el tratamiento (69,46%). Hubo un aumento en el diagnóstico materno durante la atención prenatal (16,61%) y una reducción en las muertes de niños por sífilis (31,25%). Se observó una concentración de casos en las regiones Metropolitana y de Pato Branco. En resumen, las mujeres embarazadas se encontraban en edad reproductiva, tenían bajo nivel de estudios y eran atendidas durante el prenatal, sin incluir su pareja. Además, se evidenció un comportamiento espacial aleatorio en las regiones de salud, con disparidad entre sífilis gestacional y congénita.

Detection of Plasmodium simium gametocytes in non-human primates from the Brazilian Atlantic Forest.

BACKGROUND: Plasmodium species of non-human primates (NHP) are of great interest because they can naturally infect humans. Plasmodium simium, a parasite restricted to the Brazilian Atlantic Forest, was recently shown to cause a zoonotic outbreak in the state of Rio de Janeiro. The potential of NHP to act as reservoirs of Plasmodium infection presents a challenge for malaria elimination, as NHP will contribute to the persistence of the parasite. The aim of the current study was to identify and quantify gametocytes in NHP naturally-infected by P. simium. METHODS: Whole blood samples from 35 NHP were used in quantitative reverse transcription PCR (RT-qPCR) assays targeting 18S rRNA, Pss25 and Pss48/45 malaria parasite transcripts. Absolute quantification was performed in positive samples for 18S rRNA and Pss25 targets. Linear regression was used to compare the quantification cycle (Cq) and the Spearman's rank correlation coefficient was used to assess the correlation between the copy numbers of 18S rRNA and Pss25 transcripts. The number of gametocytes/µL was calculated by applying a conversion factor of 4.17 Pss25 transcript copies per gametocyte. RESULTS: Overall, 87.5% of the 26 samples, previously diagnosed as P. simium, were positive for 18S rRNA transcript amplification, of which 13 samples (62%) were positive for Pss25 transcript amplification and 7 samples (54%) were also positive for Pss48/45 transcript. A strong positive correlation was identified between the Cq of the 18S rRNA and Pss25 and between the Pss25 and Pss48/45 transcripts. The 18S rRNA and Pss25 transcripts had an average of 1665.88 and 3.07 copies/µL, respectively. A positive correlation was observed between the copy number of Pss25 and 18S rRNA transcripts. Almost all gametocyte carriers exhibited low numbers of gametocytes (< 1/µL), with only one howler monkey having 5.8 gametocytes/µL. CONCLUSIONS: For the first time, a molecular detection of P. simium gametocytes in the blood of naturally-infected brown howler monkeys (Alouatta guariba clamitans) was reported here, providing evidence that they are likely to be infectious and transmit P. simium infection, and, therefore, may act as a reservoir of malaria infection for humans in the Brazilian Atlantic Forest.

Maternal and congenital syphilis in Indigenous Peoples: a scoping review of the worldwide literature.

BACKGROUND: Syphilis is among the most common sexually transmitted infections worldwide. When it occurs during pregnancy, it can seriously affect the fetus and newborn`s health. The scarcity of studies on maternal and congenital syphilis in Indigenous Peoples remains an obstacle to its control in these populations. This study aimed to explore the breadth of the literature, map updated evidence, and identify knowledge gaps on maternal and congenital syphilis in Indigenous Peoples worldwide. METHODS: We conducted a Scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Extension for Scoping Reviews. In March 2021, we collected data through a priority search on PubMed, Web of Science, Embase, and SciELO. RESULTS: The strategy yielded 24 studies for analysis. Data in the articles were collected from 1989 to 2020, half from 2015 onwards. Studies were in Oceania and the Americas, mainly in South America (66.7%), particularly in Brazil (50.0%). The topics assessed were Data quality related to maternal and congenital syphilis (20.8%); Diagnosis, provision, access, and use of health services (62.5%); Disease frequency and health inequities (54.2%); Determinants of maternal syphilis and congenital syphilis (20.8%); and Outcomes of maternal and congenital syphilis in the fetus (20.8%). The results show that the available literature on maternal and congenital syphilis is sparse and concentrated in some geographic areas; the frequency of these diseases in Indigenous Peoples varies but is generally higher than in the non-indigenous counterparts; the quality of surveillance data and health information systems is poor; multiple healthcare barriers exist; and the diversity of terms to identify Indigenous Peoples is a challenge to mapping scientific outputs on Indigenous Peoples' health. CONCLUSIONS: Maternal and congenital syphilis in Indigenous Peoples is a double-neglected condition and research in this area should be given the priority and encouragement it deserves globally. Reliable data and improving access to health care are needed to reduce the burden of syphilis and correctly inform policies and health services response to mitigate ethnic-racial inequalities in maternal and congenital syphilis.

The crucial role of the partner in the incidence of cases of congenital syphilis in the state of Sergipe: an analysis in 17 years / O papel crucial do parceiro na incidência dos casos de sífilis congênita no estado de Sergipe: uma análise em 17 anos

Introduction: Congenital syphilis is a highly preventable infectious disease. The relevance of the partner in the transmission of the disease is undeniable, and the underestimation of its treatment is a great risk with serious fetal consequences. Objective: The aim of this study was to analyze the partner's contribution to the inadequate treatment of pregnant women and the incidence of cases of congenital syphilis in Sergipe between 2005 and 2022. Methods: A cross-sectional, retrospective, and descriptive study was carried out through the collection of reported cases of congenital syphilis from the Notifiable Diseases Information System (SINAN). Results: There was a considerable increase in the number of reported cases of congenital syphilis in Sergipe in the past 17 years, with a predominance of untreated partners (61.5%) over treated ones (14.9%), excluding the 23.6% who had this information ignored. The variations presented from 2018 onwards stand out, resulting from the softening implemented in the notification of partner data, with an average of 23.7% of ignored information. Consequently, the diagnosis of recent congenital syphilis was found in 83.7% of newborns whose parents were not treated, in addition to 50% of cases of late infection and the vast majority of cases of stillbirths/abortion (92.6%) and deaths from the disease (78.8%). Furthermore, the non-inclusion of the partner in prenatal care (83%) contributed mainly to delays in the diagnosis of maternal syphilis, with 90.1% during delivery/curettage, 76.7% after delivery, and 77.2% of them not even identified with the disease. Conclusion: In addition to the increase in cases of congenital syphilis, there was a predominance of untreated partners, coinciding with changes in the notification criteria in 2018, which contributed to most cases of delay in maternal diagnosis, reinfection, and vertical transmission. Thus, the partner's approach is essential to guarantee the treatment and interruption of the transmission of the disease

Introdução: A sífilis congênita é uma doença infectocontagiosa altamente prevenível. A relevância do parceiro na transmissão da doença é inegável, sendo a subestimação do seu tratamento um grande risco, com graves consequências fetais. Objetivo: Analisar a contribuição do parceiro na inadequação do tratamento da gestante e na incidência dos casos de sífilis congênita em Sergipe entre 2005 e 2022. Métodos: Realizou-se um estudo transversal, retrospectivo e descritivo, através da coleta de casos notificados de sífilis congênita do Sistema de Informação de Agravos de Notificação (SINAN). Resultados: Observou-se um aumento considerável do número de casos notificados de sífilis congênita em Sergipe nos últimos 17 anos, com o predomínio de parceiros não tratados (61,5%) em relação aos tratados (14,9%), descontando-se os 23,6% que tiveram essa informação ignorada. Destacam-se as variações apresentadas a partir de 2018, decorrentes da amenização implementada na notificação dos dados do parceiro, com uma média de 23,7% de informações ignoradas. Consequentemente, o diagnóstico de sífilis congênita recente foi encontrado em 83,7% dos recém-nascidos cujos pais não foram tratados, além de 50% dos casos de infecção tardia e a maioria dos casos de natimortos/aborto (92,6%) e óbitos pelo agravo (78,8%). Outrossim, a não inclusão do parceiro na assistência pré-natal (83%) contribuiu majoritariamente nos atrasos no diagnóstico da sífilis materna, sendo 90,1% no parto/curetagem, 76,7% após o parto, além de 77,2% delas que nem mesmo foram identificadas com a doença. Conclusão: Além do aumento de casos de sífilis congênita, houve predomínio de parceiros não tratados, coincidindo com as mudanças nos critérios de notificação em 2018, o que contribuiu para a maioria dos casos de atraso no diagnóstico materno, reinfecção e transmissão vertical. Assim, a abordagem do parceiro é imprescindível para garantia do tratamento e da interrupção da transmissão da doença

Evaluating elimination of mother-to-child transmission of HIV in Suriname: a mixed method study / Estudio con métodos mixtos para evaluar la eliminación de la transmisión maternoinfantil del VIH en Suriname / Avaliação da eliminação da transmissão materno-infantil do HIV no Suriname: estudo de métodos mistos

ABSTRACT Objectives. To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants. Methods. A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15-49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed. Results. In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6-215.3) and the child (OR 145.7, 95% CI 14.4-1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4-0.7) compared with urban living. Conclusions. HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

RESUMEN Objetivos. Evaluar la secuencia de la atención para la eliminación de la transmisión maternoinfantil del virus de la inmunodeficiencia humana (VIH) en Suriname y determinar los factores sociodemográficos y clínicos que previenen la transmisión a lactantes expuestos al virus. Métodos. En este estudio se empleó un diseño de métodos mixtos. Se utilizaron los datos de atención prenatal procedentes de la encuesta transversal de indicadores múltiples por conglomerados del 2018, realizada en 1 026 mujeres de entre 15 y 49 años que habían dado a luz a un nacido vivo en los dos años anteriores. También se evaluaron los datos nacionales correspondientes a una cohorte de 279 madres con infección por el VIH y sus 317 bebés nacidos entre el 2016 y el 2018. Además, se analizaron en detalle 13 casos de transmisión maternoinfantil del VIH. Resultados. En el 89,3% de los casos no hubo transmisión maternoinfantil del VIH. En las etapas iniciales de la secuencia de la atención se observó que el 28,4% de las mujeres no tenían cubiertas sus necesidades de planificación familiar; además, el 15% no dispusieron de consultas de atención prenatal, el 8% dieron a luz fuera de un centro de salud y en el 71,5% se llevó a cabo una prueba de detección del VIH en el marco de la atención prenatal. De las mujeres embarazadas con infección por el VIH, el 84,2% recibió un tratamiento antirretroviral, mientras que el 95,5% de los bebés recibieron un tratamiento profiláctico contra el VIH. La administración de tratamiento antirretroviral a la madre (cociente de posibilidades [OR] = 45,4; intervalo de confianza [IC] del 95%: 9,6-215,3) y al bebé (OR = 145,7; IC del 95%: 14,4-1477,4) hizo que aumentaran significativamente las posibilidades de obtener un resultado negativo en la prueba de detección del VIH en los lactantes. Por el contrario, residir en el interior del país hizo que disminuyeran dichas posibilidades (OR = 0,2; IC del 95%: 0,4-0,7), en comparación con residir en un entorno urbano. Conclusiones. Para las madres con infección por el VIH y para sus bebés, los medicamentos contra el VIH siguen siendo esenciales para prevenir la transmisión maternoinfantil del VIH. En Suriname debe reforzarse la atención prenatal temprana, incluido el seguimiento.

RESUMO Objetivos. Avaliar a cascata de atendimento para a eliminação da transmissão materno-infantil do vírus da imunodeficiência humana (HIV) no Suriname e identificar fatores sociodemográficos e clínicos que impedem a transmissão a bebês expostos. Métodos. Foi utilizado um delineamento de estudo com métodos mistos. Foram usados dados de atendimento pré-natal de uma pesquisa de indicadores múltiplos por conglomerados de corte transversal realizada em 2018, que incluiu 1 026 mulheres com idades entre 15 e 49 anos que haviam tido um nascido vivo nos dois anos anteriores. Além disso, foram avaliados os dados nacionais de uma coorte de 279 mães com HIV e seus 317 bebês nascidos vivos de 2016 a 2018, além de 13 casos de transmissão materno-infantil de HIV. Resultados. Em 89,3% dos casos, não houve transmissão materno-infantil do HIV. As etapas iniciais da cascata demonstram que 28,4% das mulheres tiveram necessidades não atendidas de planejamento familiar, 15% não fizeram consultas pré-natais, 8% tiveram o parto fora de uma unidade de saúde e 71,5% receberam um teste de HIV durante o atendimento pré-natal. Das gestantes com HIV, 84,2% receberam terapia antirretroviral, e 95,5% de seus bebês receberam tratamento profilático para o HIV. O tratamento antirretroviral da mãe (razão de chances [RC]: 45,4; intervalo de confiança [IC] de 95%: 9,6-215,3) e da criança (RC: 145,7; IC 95%: 14,4-1477,4) aumentou significativamente a probabilidade de um resultado negativo no teste de HIV dos bebês. Por outro lado, morar no interior diminuiu a probabilidade (RC: 0,2; IC 95%: 0,4-0,7) em comparação com o ambiente urbano. Conclusões. A medicação de mães e bebês contra o HIV continua sendo fundamental para a prevenção da transmissão materno-infantil do HIV. Deve-se reforçar o atendimento pré-natal precoce com acompanhamento no Suriname.

Clinical and serological findings in pregnant women and newborns: patterns of coronavirus disease 2019 placental histopathology

SUMMARY OBJECTIVE: The objective of this study was to evaluate the correlation between clinical and serological findings of pregnant women and newborns with patterns of histopathologic changes of the placenta diagnosed with coronavirus disease 2019. METHODS: A prospective descriptive study was conducted with pregnant women who were positive for SARS-CoV-2 by reverse transcription polymerase chain reaction or serology (IgG and IgM). Clinical analyses were performed using ELISA to detect anti-SARS-CoV-2 IgG and IgA antibodies using the S1 spike protein domain with the Euroimmun kit. Histopathologic analyses of placentas were performed by two expert pathologists. RESULTS: Maternal SARS-CoV-2 infection was associated with increased neonatal hospital length of stay (p=0.03), increased preterm birth (p=0.04), and Apgar score<7 at 1st min (p=0.00) and 5th min (p=0.02). Pregnant women with positive IgG and/or IgA at delivery had a higher incidence of placental histopathologic changes in addition to a greater likelihood of having an IgG-positive fetus (p<0.0001). Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion changes (p=0.00). CONCLUSION: Maternal SARS-CoV-2 infection was associated with adverse perinatal outcomes. Pregnant women with positive IgG at delivery had a higher incidence of placental histopathologic changes. Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion.

Screening for coronavirus disease 2019 in pregnant women admitted for delivery: an observational study

SUMMARY OBJECTIVE: The aim of this study was to examine the impact of symptom-based screening on the prevalence and outcomes of neonatal coronavirus disease 2019 in pregnant women admitted for delivery. METHODS: A retrospective observational study was conducted from June to August 2020 at Gonzaga Mota of Messejana Hospital, Fortaleza, CE, Brazil. All pregnant women were screened for coronavirus disease 2019 based on symptoms. Reverse transcription-polymerase chain reaction or immunology assays for severe acute respiratory syndrome coronavirus 2 were performed when a patient reported a symptom. All newborns of symptomatic patients were submitted for Reverse transcription-polymerase chain reaction. Newborns were divided into groups according to the Reverse transcription-polymerase chain reaction results to identify the relationship between maternal symptoms and neonatal coronavirus disease 2019. RESULTS: A total of 55 (55/1,026, 5.4%) and 50 (50/1,026, 4.8%) pregnant women reported symptoms and had a positive confirmatory test, respectively. The most common symptom of coronavirus disease 2019 among the pregnant women with positive confirmatory test was cough (n=23, 46%). Seven newborns (7/50, 14%) of symptomatic mothers had positive Reverse transcription-polymerase chain reaction. Upon birth, no newborn had serious complications. CONCLUSION: Universal screening of pregnant women admitted for delivery can reduce the perinatal transmission of coronavirus disease 2019. Symptom-based screening can be an alternative for regions with a low prevalence of the disease where a better allocation of financial resources is necessary.

Vacuna del virus del papiloma humano: valoración bioética de la discriminación por sexo

La infección por el virus del papiloma humano (VPH) constituye la causa necesaria, aunque no suficiente, de la enfermedad de transmisión sexual más frecuente en el mundo, responsable del 4,5 % de todos los cánceres en ambos sexos. La vacunación frente al VPH, con niveles de eficacia y seguridad similares en ambos sexos, está dirigida básicamente a mujeres, para reducir la incidencia de infección y sus consecuencias, como el cáncer de cérvix. La transmisibilidad del virus en ambos sexos y la inmunidad colectiva que proporciona la vacunación universal hace que su extensión al sexo masculino constituya una cuestión no solo de salud pública, sino también un dilema bioético relacionado con la protección de la salud y la equitativa distribución de los recursos. Este trabajo aborda el análisis bioético de la extensión de la vacunación contra VPH a ambos sexos.

Human Papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide, responsible for 4.5 % of all cancers in both sexes. HPV vaccination, with similar levels of efficacy and safety in both sexes, is aimed at women to prevent cervical cancer. The transmissibility of the virus in both sexes and the herd immunity provided by universal vaccination makes its extension to the male sex a matter not only of public health but also a bioethical dilemma related to the protection of health and the equitable distribution of resources. This research addresses the bioethical analysis of the extension of HPV vaccination to both sexes.

A infecção pelo vírus do papiloma humano (HPV, na sigla em inglês) constitui a causa principal, ainda que não suficiente, da doença de transmissão sexual mais frequente no mundo, responsável por 4,5 % de todos os cânceres em ambos os sexos. A vacinação contra o HPV, com níveis de eficácia e segurança semelhantes em ambos os sexos, está orientada basicamente a mulheres, para reduzir a incidência de infecção e suas consequências, como o câncer do colo do útero. A transmissão do vírus em ambos os sexos e a imunidade coletiva que a vacinação universal promove fazem com que sua extensão ao sexo masculino constitua uma questão não apenas de saúde pública, mas também um dilema bioético relacionado com a proteção da saúde e a equitativa distribuição dos recursos. Nesse sentido, neste trabalho, é abordada a análise bioética da extensão da vacinação contra o HPV em ambos os sexos.

Dinámica de la transmisión de SARS-CoV-2 en centros educativos en un prestador de salud privado en Uruguay / Transmission dynamics of SARS-CoV-2 in schools assisted by one health service provider in Uruguay / Dinâmica da transmissão do SARS-CoV-2 em centros educacionais para o caso dum provedor de saúde privado no Uruguai

Introducción: en Uruguay se registró entre diciembre de 2020 y marzo de 2021 un aumento sostenido en la transmisión comunitaria del virus SARS-CoV-2, llegando a un índice de Harvard IP7 de 24,07. Considerando las consecuencias negativas del cierre escolar y que, a diferencia de los adultos, los niños son menos vulnerables y transmiten menos la infección, a pesar del contexto epidemiológico se decidió retomar la presencialidad parcial en centros educativos. Resulta necesario analizar las características de la transmisión en dichos centros para evaluar el impacto de las medidas de mitigación. Objetivo: describir las características de la transmisión de la infección por SARS-CoV-2 en una serie de niños asistidos en un prestador privado de salud con exposición de riesgo en centros educativos. Metodología: estudio descriptivo y retrospectivo de los menores de 15 años con infección por SARS-CoV-2 con exposición de riesgo en centros educativos asistidos en marzo de 2021. Se describieron variables clínicas (edad, sexo, manifestaciones clínicas, evolución), características de la exposición (caso índice, cumplimiento de medidas de distanciamiento físico, uso de mascarilla) y casos secundarios. La fuente de datos fue la historia clínica complementada con encuesta telefónica a madre, padre y/o tutor. Resultados: presentaron exposición de riesgo en centros educativos 198 de los 804 menores de 15 años con infección por SARS-CoV-2 (24,6%). Media edad 8 años, 51% de sexo femenino. Fueron asintomáticos 53% y presentaron síntomas leves 47%. Ninguno requirió hospitalización ni presentó complicaciones post infecciosas al momento de la comunicación. El caso índice fue un adulto en 64% y un niño en 36%. Refirieron haber cumplido medidas de distanciamiento físico 45% y uso de mascarilla 60%. En el 45% se produjeron casos secundarios en el hogar, uno de ellos falleció (65 años, diabetes mellitus tipo 2). Conclusiones: en este escenario con elevados índices de circulación comunitaria, más de la cuarta parte de los niños de esta serie adquirieron la infección en un centro educativo, mayoritariamente a partir de un adulto. Si bien la mayoría de los niños fueron asintomáticos o desarrollaron formas leves de la enfermedad, una proporción importante continuó la cadena de transmisión y generó casos secundarios intradomiciliarios. Es posible que el incumplimiento de las medidas de distanciamiento físico y en el uso de mascarilla sumado a la circulación de la VOC gamma (P1) en etapas tempranas de la campaña de vacunación, expliquen estos hallazgos. El análisis de la dinámica de la transmisión resulta imprescindible para optimizar las medidas de mitigación de la pandemia.

Introduction: in Uruguay, between December 2020 and March 2021, there was a steady increase in community transmission of the SARS-CoV-2 virus when it reached a Harvard IP7 index of 24.07. Considering the negative consequences of closing down schools and the fact that, unlike adults, children are less vulnerable and transmit the infection less, it was decided to resume partial school attendance, despite the epidemiological situation. It is necessary to analyze the characteristics of the transmission in these centers to evaluate the impact of the mitigation measures. Objective: describe the characteristics of the transmission of SARS CoV-2 infection in several children at risk of exposure at their schools and assisted by a private health provider. Methodology: descriptive, retrospective study of children under 15 years of age with SARS-CoV-2 infection at risk exposure at educational centers in March 2021. Clinical variables (age, sex, clinical manifestations, evolution), characteristics of exposure (index case, compliance with physical distancing measures, wear of face masks) and secondary cases. The data source was health medical records and a supplementary telephone survey to the mother, father and/or guardian. Results: 198 of the 804 children under 15 years of age with SARS-CoV-2 infection (24.6%) presented risk exposure at their educational centers. Average age 8 years, 51% female. 53% were asymptomatic and 47% had mild symptoms. None required hospitalization or presented post-infectious complications at the time of communication. The index case was an adult in 64% and a child in 36%. They reported having complied with physical distance restrictions 45% and use of a mask 60%. In 45% secondary cases occurred at home, one of them died (65 years old, type 2 diabetes mellitus). Conclusions: in this scenario with high rates of community circulation, more than a quarter of the children in this series acquired the infection in an educational center, mostly from an adult. Although most of the children were asymptomatic or developed mild forms of the disease, a significant proportion continued the chain of transmission and generated secondary intradomiciliary cases. It is possible that lack of compliance with physical distancing protocols and with the use of the mask, added to the circulation of gamma VOC (P1) in the early stages of the vaccination campaign and can explain these findings. Analysis of the transmission dynamics is essential to optimize pandemic mitigation measures.

Introdução: no Uruguai, entre dezembro de 2020 e março de 2021, houve um aumento gradativo da transmissão comunitária do vírus SARS-CoV-2, atingindo um índice Harvard IP7 de 24,07. Considerando as consequências negativas do encerramento das escolas e que, ao contrário dos adultos, as crianças são menos vulneráveis e transmitem menos a infecção, apesar do contexto epidemiológico, decidiu-se retomar a presença parcial nos centros educativos. É necessário analisar as características da transmissão nesses centros para avaliar o impacto das medidas de mitigação. Objetivo: descrever as características da transmissão da infecção por SARS CoV-2 em uma série de crianças atendidas numa assistência privada de saúde com exposição de risco em centros educacionais. Metodologia: estudo descritivo, retrospectivo de crianças menores de 15 anos de idade com infecção por SARS-CoV-2 com exposição de risco em centros educacionais atendidos em março de 2021. Variáveis clínicas (idade, sexo, manifestações clínicas, evolução), características da exposição (caso índice), cumprimento das medidas de distanciamento físico, uso de máscara) e casos secundários. A fonte de dados foi a história clínica complementada por uma enquete telefônica à mãe, pai e/ou responsável. Resultados: 198 das 804 crianças menores de 15 anos com infecção por SARS-CoV-2 (24,6%) apresentaram exposição de risco em centros educacionais. Idade média 8 anos, 51% do sexo feminino. 53% eram assintomáticas e 47% apresentavam sintomas leves. Nenhuma delas precisou de internação ou apresentou complicações pós-infecciosas no momento da comunicação. O caso índice foi um adulto em 64% e uma criança em 36%. Relataram ter cumprido as medidas de distanciamento físico 45% e uso de máscara 60%. Em 45% dos casos secundários ocorreram em casa, um deles faleceu (65 anos, diabetes mellitus tipo 2). Conclusões: neste cenário com altas taxas de circulação comunitária, mais de um quarto das crianças desta série adquiriram a infecção em um centro educacional, principalmente de um adulto. Embora a maioria das crianças fosse assintomática ou desenvolvesse formas leves da doença, uma proporção significativa continuou a cadeia de transmissão e gerou casos secundários intradomiciliares. É possível que a falta de cumprimento das medidas de distanciamento físico e do uso de máscara, somados à circulação de VOC gama (P1) nas fases iniciais da campanha de vacinação, expliquem esses achados. A análise da dinâmica de transmissão é essencial para otimizar as medidas de mitigação da pandemia.
