RESUMO
OBJECTIVE: To describe the profile of cases of mpox in the city of Rio de Janeiro between June and November 2022. METHODS: This was a descriptive study of secondary data obtained from mpox notification forms. Socioeconomic, clinical and spatial data were analyzed. RESULTS: Of the 928 cases, 93.7% were male, 85.0% cisgender male, 65.6% homosexual, 41.8% between 30 and 39 years old, and 41.0% were of White race/skin color. A total of 34.5% had immunosuppression due to illness, and 41.9% reported their HIV status as being positive. The most prevalent signs and symptoms were: skin lesions (96.6%), especially with multiple manifestations (67.8%) in the genital region (46.1%), in addition to fever (58.3%), adenomegaly (43.3%) and headache (38.7%). Most notifications occurred in public services (81.3%) and in hospital care (51.3%). CONCLUSION: The study revealed high incidence of mpox, especially among young, cisgender and homosexual men. Most cases were mild, with genital lesions, progressing to cure without hospitalization. Person-to-person transmission was predominant.

RESUMO
MAIN RESULTS: An outbreak of illness compatible with scurvy occurred among male prison inmates; most frequent signs/symptoms were edema and pain in lower limbs, difficulty in walking and hematoma/ecchymosis; the associated factor was age > 40 years. IMPLICATIONS FOR SERVICES: The results can contribute to the identification and description of scurvy outbreaks in other contexts and territories. Epidemiological studies of events like this enhance the practice of field epidemiology in health services. PERSPECTIVES: It is expected that the prevention of hypovitaminosis, such as scurvy, will be based on public policies aimed at the population deprived of liberty; and that the capabilities of health services to detect and respond to cases of the disease will be improved. OBJECTIVE: to identify the occurrence of an outbreak compatible with scurvy and exposure factors associated with typical signs/symptoms of hypovitaminosis that occurred in a male penitentiary in Ceará, Brazil between 2019-2020. METHODS: this was a population-based case-control study; we used clinical records and interviews with compatible cases - based on sign/symptom onset during the study period - and with controls; we carried out multivariate analysis. RESULTS: out of 62 cases, mean age was 40.6 years (SD = 10.8); main signs/symptoms were edema and pain in the lower limbs (100.0%), difficulty in walking (91.9%), hematoma/ecchymosis in the lower limbs (90.3%) and fever (88.7%); we identified being over 40 years old as an associated factor (aOR = 1.10; 95%CI 1.05;1.17; p-value = 0.001); and as protective factors: working (aOR = 0.11; 95%CI 0.03;0.36; p-value < 0.001) and taking part in classes (aOR = 0.21; 95%CI 0.08;0.59; p-value = 0.003) in the prison. CONCLUSION: we considered the penitentiary outbreak to be compatible with scurvy due to characteristic signs/symptoms, associated with the identified factors; we recommended regular provision of a diet rich in vitamin C to all male inmates and clinical follow-up of cases.

OBJECTIVE: To evaluate excess mortality in the city of Rio de Janeiro, Brazil, due to the COVID-19 pandemic (March 2020 to January 2022). METHODS: Ecological study using secondary data from the Brazilian Mortality Information System, having the city of Rio de Janeiro as the unit of analysis. Excess mortality was estimated by the difference between the mean number of all expected deaths and the mean number of observed deaths, considering the 2015-2019 period. The quantile regression method was adjusted. The total value of cases above that expected by the historical series was estimated. Among all deaths, cases of COVID-19 and Influenza as underlying causes of death were selected. The ratio between excess mortality and deaths due to COVID-19 was calculated. RESULTS: We identified an excess of 31,920 deaths by the mean (increase of 26.8%). The regression pointed to 31,363 excess deaths. We found 33,401 deaths from COVID-19 and 176 deaths from Influenza. The ratio between the verified excess mortality and deaths due to COVID-19 was 0.96 by the mean and 0.95 by the regression. CONCLUSION: The study pointed to large excess deaths during the COVID-19 pandemic in the city of Rio de Janeiro distributed in waves, including the period of the Influenza outbreak.

Background: A vaccination campaign targeted adults in response to the pandemic in the City of Rio de Janeiro. Objective: We aimed to evaluate the seroprevalence of SARS-CoV-2 antibodies and identify factors associated with seropositivity on vaccinated and unvaccinated residents. Methods: We performed a seroepidemiologic survey in all residents of Paquetá Island, a neighborhood of Rio de Janeiro city, during the COVID-19 vaccine roll-out. Serological tests were performed from June 16 to June 19, 2021, and adjusted seropositivity rates were estimated by age and epidemiological variables. Logistic regression models were used to estimate adjusted ORs for risk factors to SARS-CoV-2 seropositivity in non-vaccinated individuals, and potential determinants of the magnitude of antibody responses in the seropositive population. Results: We included in the study 3,016 residents of Paquetá (83.5% of the island population). The crude seroprevalence of COVID-19 antibodies in our sample was 53.6% (95% CI = 51.0, 56.3). The risk factors for SARS-CoV-2 seropositivity in non-vaccinated individuals were history of confirmed previous COVID-19 infection (OR = 4.74; 95% CI = 3.3, 7.0), being a household contact of a case (OR = 1.93; 95% CI = 1.5, 2.6) and in-person learning (OR = 2.01; 95% CI = 1.4, 3.0). Potential determinants of the magnitude of antibody responses among the seropositive were hybrid immunity, the type of vaccine received, and time since the last vaccine dose. Being vaccinated with Pfizer or AstraZeneca (Beta = 2.2; 95% CI = 1.8, 2.6) determined higher antibody titers than those observed with CoronaVac (Beta = 1.2; 95% CI = 0.9, 1.5). Conclusions: Our study highlights the impact of vaccination on COVID-19 collective immunity even in a highly affected population, showing the difference in antibody titers achieved with different vaccines and how they wane with time, reinforcing how these factors should be considered when estimating effectiveness of a vaccination program at any given time. We also found that hybrid immunity was superior to both infection-induced and vaccine-induced immunity alone, and online learning protected students from COVID-19 exposure.

In this study, we report the first case of intra-host SARS-CoV-2 recombination during a coinfection by the variants of concern (VOC) AY.33 (Delta) and P.1 (Gamma) supported by sequencing reads harboring a mosaic of lineage-defining mutations. By using next-generation sequencing reads intersecting regions that simultaneously overlap lineage-defining mutations from Gamma and Delta, we were able to identify a total of six recombinant regions across the SARS-CoV-2 genome within a sample. Four of them mapped in the spike gene and two in the nucleocapsid gene. We detected mosaic reads harboring a combination of lineage-defining mutations from each VOC. To our knowledge, this is the first report of intra-host RNA-RNA recombination between two lineages of SARS-CoV-2, which can represent a threat to public health management during the COVID-19 pandemic due to the possibility of the emergence of viruses with recombinant phenotypes.

In the present study, we provide a retrospective genomic epidemiology analysis of the SARS-CoV-2 pandemic in the state of Rio de Janeiro, Brazil. We gathered publicly available data from GISAID and sequenced 1927 new genomes sampled periodically from March 2021 to June 2021 from 91 out of the 92 cities of the state. Our results showed that the pandemic was characterized by three different phases driven by a successive replacement of lineages. Interestingly, we noticed that viral supercarriers accounted for the overwhelming majority of the circulating virus (>90%) among symptomatic individuals in the state. Moreover, SARS-CoV-2 genomic surveillance also revealed the emergence and spread of two new variants (P.5 and P.1.2), firstly reported in this study. Our findings provided important lessons learned from the different epidemiological aspects of the SARS-CoV-2 dynamic in Rio de Janeiro. Altogether, this might have a strong potential to shape future decisions aiming to improve public health management and understanding mechanisms underlying virus dispersion.

OBJECTIVE: to describe the temporal and spatial distribution of reported and confirmed cases of congenital Zika virus syndrome (CZS) in live births in Brazil during 2015-2016. METHODS: we conducted a descriptive study with data from the Public Health Events Registry, including cases born in 2015 or 2016, and registered between epidemiological week 45/2015 and 2/2017. RESULTS: we analyzed 9.953 reported cases, of which 2.018 (20.3%) were confirmed and 2.819 (28.3%) were still under investigation at the epidemiological week 2/2017; 404 (4.1%) out of the 9.953 cases had laboratory confirmation for Zika virus; the prevalence of confirmed cases of CZS was 3.8/10 thousand livebirths in 2015 and 3.1/10 thousand live births in 2016. CONCLUSION: one fifth of the cases reported in 2015-16 were confirmed the CZS, reinforcing their relevance as a public health problem; efforts aimed at the diagnostic confirmation of the syndrome should be prioritized.

OBJECTIVE: to describe the results of Rapid Monitoring Vaccination monitoring conducted with the aim of interrupting the measles outbreak in the State of Ceará, Brazil, in 2015. METHODS: this was a descriptive study using data taken from 52,216 vaccination cards of children aged from 6 months to less than 5 years and data on vaccination coverage, homogeneity, and reasons for non-vaccination extracted from the National Immunization Program Information System (SI-PNI). RESULTS: vaccination coverage against measles reached 96.7% in Ceará; of the 21 Regional Health Offices in the State, four did not reach minimum coverage of 95% for the first dose, and two for the second dose; 836 children (1.6%) were not vaccinated and 1,388 vaccine doses were not used. CONCLUSION: Measles vaccination campaigns enabled the immunization coverage goal in the State of Ceará to be surpassed, despite the considerable number of unvaccinated children found.

ABSTRACT Objective To propose and test a model for analyzing municipalities' level of risk of reintroduction and transmission of the measles virus in the post-elimination period in the Americas. Methods An ecological-analytical study was conducted using data on the measles epidemic that occurred in 2013-2015 in northeastern Brazil. The variables for analysis were selected after an extensive review of scientific literature on the risk of importation of measles cases. A univariate analysis considering the presence or absence of confirmed cases of measles in 184 municipalities in the state of Ceará, Brazil, was carried out to evaluate the association between the dependent variable and 23 independent variables, grouped into four categories: 1) characteristics of the municipalities; 2) quality indicators for immunization programs and epidemiological surveillance; 3) organizational structure for the public health response; and 4) selected impact indicators. A P value < 0.05 was considered significant. All variables with P < 0.200 were analyzed using multivariate logistic regression. Based on the results, the municipalities were categorized by four levels of risk ("low," "medium," "high," and "very high"). Results The model sensitivity was 95% for concordance between municipalities classified as "high risk" and "very high risk" and those that had an epidemic between 2013 and 2015 in Ceará. Of the 38 municipalities that had an epidemic, 76% (29/38) were classified as "high risk" and "very high risk"; 146 municipalities did not report cases (P < 0.0002). Conclusions Given the imminent risk of reintroduction of measles circulation in the post-elimination period in the Americas, this model may be useful in identifying areas at greater risk for reintroduction and continued transmission of measles. Knowledge of vulnerable areas could trigger appropriate surveillance and monitoring to prevent sustained transmission.
RESUMEN Objetivo Proponer y poner a prueba un modelo para analizar el nivel de riesgo de reintroducción y transmisión del virus del sarampión que existe en los municipios durante el período posterior a la eliminación en la Región de las Américas. Métodos Se realizó un estudio ecológico y analítico empleando datos sobre la epidemia de sarampión que afectó al noreste del Brasil del 2013 al 2015. Las variables para el análisis se seleccionaron después de efectuar un amplio examen de las publicaciones científicas sobre el riesgo de importación de casos de sarampión. Se llevó a cabo un análisis con una sola variable considerando la presencia o ausencia de los casos de sarampión confirmados en 184 municipios del estado de Ceará (Brasil) para evaluar la asociación entre la variable dependiente y 23 variables independientes, que se agruparon en cuatro categorías: 1) características de los municipios; 2) indicadores de calidad de los programas de vacunación y la vigilancia epidemiológica; 3) estructura de organización de la respuesta de salud pública, y 4) indicadores del impacto seleccionados. Se consideró significativo un valor de P < 0,05. Todas las variables con un valor P < 0,200 se analizaron empleando una regresión logística con varias variables. Teniendo en cuenta los resultados, los municipios se clasificaron en función de cuatro niveles de riesgo ("bajo", "medio", "alto" y "muy alto"). Resultados El modelo tenía una sensibilidad de 95% en el caso de la concordancia entre los municipios clasificados dentro de las categorías de "riesgo alto" y "riesgo muy alto" y los que tuvieron una epidemia entre el 2013 y el 2015 en Ceará. De los 38 municipios que tuvieron una epidemia, 76% (29/38) se clasificaron dentro de las categorías de "riesgo alto" y "riesgo muy alto"; 146 municipios no notificaron casos (P < 0,0002). Conclusiones Dado el riesgo inminente de reintroducción de la circulación del sarampión durante el período posterior a la eliminación en la Región de las Américas, este modelo puede ser útil para reconocer las zonas en las que existe un mayor riesgo de reintroducción y transmisión continua del sarampión. El conocimiento de las zonas vulnerables podría desembocar en actividades de vigilancia y seguimiento apropiadas para evitar la transmisión sostenida.
RESUMO Objetivo Elaborar e testar um modelo para analisar o risco de reintrodução e transmissão do vírus do sarampo ao nível municipal no período pós-eliminação nas Américas. Métodos Um estudo analítico-ecológico foi realizado com base nos dados da epidemia de sarampo ocorrida em 2013-2015 no nordeste do Brasil. As variáveis para análise foram selecionadas após extensa revisão da literatura científica sobre o risco de importação de casos de sarampo. Uma análise univariada considerando a presença ou a ausência de casos confirmados de sarampo em 184 municípios no Estado do Ceará foi conduzida para avaliar a associação entre a variável dependente e 23 variáveis independentes divididas em quatro grupos: 1) características dos municípios, 2) indicadores de qualidade dos programas de vacinação e da vigilância epidemiológica, 3) estrutura organizacional para resposta em saúde pública e 4) indicadores de impacto selecionados. Um nível de significância de 5% foi definido. Todas as variáveis com P < 0,200 foram analisadas por regressão logística multivariada e, segundo os resultados, os municípios foram categorizados em quatro níveis de risco: baixo, intermediário, alto e muito alto. Resultados A sensibilidade do modelo foi de 95% para concordância entre os municípios categorizados como "risco alto" e "risco muito alto" e os que registraram a ocorrência de epidemia entre 2013 e 2015 no Ceará. Dos 38 municípios onde ocorreu uma epidemia, 76% (29/38) apresentaram "risco alto" e "risco muito alto" de reintrodução e transmissão do vírus do sarampo e 146 municípios não notificaram casos (P < 0,0002). Conclusão Diante do risco iminente de reintrodução da circulação do vírus do sarampo no período pós-eliminação nas Américas, este modelo pode servir para identificar as áreas de maior risco de reintrodução e transmissão contínua do vírus do sarampo. Conhecer as áreas vulneráveis incentiva a adoção de procedimentos adequados de vigilância e monitoramento a fim de prevenir a transmissão sustentada.

An epidemic of infections after video-assisted surgery (1,051 possible cases) caused by rapidly growing mycobacteria (RGM) and involving 63 hospitals in the state of Rio de Janeiro, Brazil, occurred between August 2006 and July 2007. One hundred ninety-seven cases were confirmed by positive acid-fast staining and/or culture techniques. Thirty-eight hospitals had cases confirmed by mycobacterial culture, with a total of 148 available isolates recovered from 146 patients. Most (n = 144; 97.2%) isolates presented a PRA-hsp65 restriction pattern suggestive of Mycobacterium bolletii or Mycobacterium massiliense. Seventy-four of these isolates were further identified by hsp65 or rpoB partial sequencing, confirming the species identification as M. massiliense. Epidemic isolates showed susceptibility to amikacin (MIC at which 90% of the tested isolates are inhibited [MIC(90)], 8 microg/ml) and clarithromycin (MIC(90), 0.25 microg/ml) but resistance to ciprofloxacin (MIC(90), >or=32 microg/ml), cefoxitin (MIC(90), 128 microg/ml), and doxycycline (MIC(90), >or=64 microg/ml). Representative epidemic M. massiliense isolates that were randomly selected, including at least one isolate from each hospital where confirmed cases were detected, belonged to a single clone, as indicated by the analysis of pulsed-field gel electrophoresis (PFGE) patterns. They also had the same PFGE pattern as that previously observed in two outbreaks that occurred in other Brazilian cities; we designated this clone BRA100. All five BRA100 M. massiliense isolates tested presented consistent tolerance to 2% glutaraldehyde. This is the largest epidemic of postsurgical infections caused by RGM reported in the literature to date in Brazil.
