Chikungunya seroprevalence in population-based studies: a systematic review and meta-analysis.

BACKGROUND: Seroprevalence studies about chikungunya infection are usually conducted after epidemics to estimate the magnitude of the attack. This study aimed to estimate the seroprevalence of CHIKV by WHO region, considering the periods of introduction of the virus in these regions and its potential to lead to epidemics. METHODS: We systematically reviewed Medline/Pubmed, Embase, Lilacs, Scopus and Web of Science for original articles published up to 2020. Cohort, case-control and cross-sectional studies were eligible for inclusion, based on the results of laboratory diagnosis of previous or previous and recent infection. Those conducted with symptomatic individuals were excluded. RESULTS: 596 articles were identified, 197 full-text were reviewed and 64 were included, resulting in 71 seroprevalences. Most were cross-sectional studies (92%), between 2001 and 2020 (92%), with population of all ages (55%), conducted in Kenya (10.9%), Brazil (9.4%) and French Polynesia (7.8%). The pooled estimates were 24% (95%CI 19-29; I2 = 99.7%; p < 0.00), being 21% (95%CI 13-30; I2 = 99.5%; p < 0.00) for adults, 7% (95%CI 0-23; I2 = 99.7%; p < 0.00) for children and 30% (95%CI 23-38; I2 = 99.7%; p < 0.00) for all ages. The higher seroprevalences were found in African, the Americas and South-East Asian Regions. CONCLUSIONS: The great heterogeneity of seroprevalences points to the persistence of viral circulation. Even where the seroprevalence is high, the population replacement and the absence of vaccines mean that the risk of virus spread and epidemics remains. REGISTRATION: PROSPERO CRD42020166227.

The triple epidemics of arboviruses in Feira de Santana, Brazilian Northeast: Epidemiological characteristics and diffusion patterns.

Arboviruses are diseases of worldwide importance in the field of communicable diseases. In Brazil, the reemergence of dengue and the emergence of chikungunya and Zika since 2014 have led to epidemic waves of great magnitude and rapid spread. However, their diffusion patterns vary and change over time. This study analyzes the spatial diffusion of the simultaneous circulation of three arboviruses transmitted by the same vector in a large urban space over two epidemic waves in consecutive years. An ecological study of spatial and temporal aggregates on the occurrence of dengue, chikungunya, and Zika, from 2014 to 2019, in Feira de Santana, Bahia State, was carried out using data of cases reported to the national surveillance system. Four different methods were used to analyze the spatial diffusion: Kernel Estimation with sequential maps, cumulative nearest-neighbor ratios (NNI) over time, spatial correlograms and local autocorrelation changes (LISA) over time. From 2014-2019, there were 21,723 confirmed cases of arboviruses. The highest incidences were among women (496.9, 220.2, and 91.0 cases/100,000 women for dengue, chikungunya and Zika respectively). By age group, the highest incidences were from ages 10-19 years old (609.3 dengue cases/100,000), from 60 and more (306.7 chikungunya cases/100,000), and from 0-9 years old (124.1 Zika cases/100,000 inhabitants). The temporal distribution demonstrated two epidemic waves of simultaneous circulation in 2014 and 2015. Kernel maps indicate that arboviruses spread to neighboring areas near the first hotspots, suggesting an expansion diffusion pattern. The NNI, spatial correlograms and LISA changes results suggest expansion patterns for the three arboviruses in all periods. The spatial diffusion pattern of dengue, Zika, and chikungunya in the 2014-2015 epidemics in Feira de Santana was expansion. These findings are useful to guide prevention measures and reduce occurrence in other areas.

[Prevalence of respiratory symptoms in areas of the Federal District, Brazil]. / Prevalência de sintomáticos respiratórios em regiões do Distrito Federal, Brasil.

The identification of individuals with respiratory symptoms (RS) is important for the early detection of tuberculosis. The aim of this study was to estimate the prevalence of RS in three administrative regions of the Federal District, Brazil. For this, we used the 30 by 7 cluster sampling technique proposed by the World Health Organization. Individuals with RS were defined as those aged 15 years or older living in the administrative regions of Estrutural, Itapoã, or Varjão and reporting a cough lasting at least 3 weeks at the date of the interview. The prevalence of RS was 5.7% in Estrutural and Varjão (95% CI: 2.4-9.0) and 4.8% in Itapoã (95%CI: 1.6-7.9), with a design effect close to 1.0. In Estrutural and Itapoã, fewer years of schooling, and in Itapoã and Varjão, lower income, were associated with RS. Cigarette smoking was associated with the presence of RS in all regions. The prevalence of RS in the three administrative regions investigated is consistent with that of other areas with a similar socioeconomic profile.

Seroprevalence of Chikungunya virus and living conditions in Feira de Santana, Bahia-Brazil.

BACKGROUND: Chikungunya is an arbovirus, transmitted by Aedes mosquitoes, which emerged in the Americas in 2013 and spread rapidly to almost every country on this continent. In Brazil, where the first cases were detected in 2014, it currently has reached all regions of this country and more than 900,000 cases were reported. The clinical spectrum of chikungunya ranges from an acute self-limiting form to disabling chronic forms. The purpose of this study was to estimate the seroprevalence of chikungunya infection in a large Brazilian city and investigate the association between viral circulation and living condition. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a population-based ecological study in selected Sentinel Areas (SA) through household interviews and a serologic survey in 2016/2017. The sample was of 1,981 individuals randomly selected. The CHIKV seroprevalence was 22.1% (17.1 IgG, 2.3 IgM, and 1.4 IgG and IgM) and varied between SA from 2.0% to 70.5%. The seroprevalence was significantly lower in SA with high living conditions compared to SA with low living condition. There was a positive association between CHIKV seroprevalence and population density (r = 0.2389; p = 0.02033). CONCLUSIONS/SIGNIFICANCE: The seroprevalence in this city was 2.6 times lower than the 57% observed in a study conducted in the epicentre of the CHIKV epidemic of this same urban centre. So, the herd immunity in this general population, after four years of circulation of this agent is relatively low. It indicates that CHIKV transmission may persist in that city, either in endemic form or in the form of a new epidemic, because the vector infestation is persistent. Besides, the significantly lower seroprevalences in SA of higher Living Condition suggest that beyond the surveillance of the disease, vector control and specific actions of basic sanitation, the reduction of the incidence of this infection also depends on the improvement of the general living conditions of the population.

[Epidemiological profile of the clientele in HIV Testing and Counseling Centers in Santa Catarina State, Brazil, 2005]. / Perfil epidemiológico dos usuários dos Centros de Testagem e Aconselhamento do Estado de Santa Catarina, Brasil, no ano de 2005.

This study analyzes the user profile of HIV Testing and Counseling Centers in Santa Catarina State, Brazil, in 2005, and factors associated with HIV infection. The methodology employed a retrospective, cross-sectional study of individuals who attended Testing and Counseling Centers. Data from 22,846 interviews were analyzed (64.7% women and 35.3% men). HIV prevalence was 2.0% in women and 5.6% in men. Statistical analysis used bivariate and multivariate Poisson regression by gender. According to the Poisson regression, factors associated with HIV+ status were age bracket, schooling, marital status, professional situation, population group, steady partner's risk status, condom use, and reason for not using condoms with steady partner; for men, the independent variables were age bracket, schooling, type of partner, population group, steady partner's risk status, condom use, and reason for not using condoms with steady partner. HIV+ patterns differed between men and women, so that customized preventive approaches are needed.

Introdução: A microcefalia é uma condição neurológica que se caracteriza por anormalidades no crescimento craniano e pode ser causada por vários fatores como a desnutrição, o uso de drogas, as infecções e mais recentemente pela contaminação pelo Zika Vírus. Apenas em 2015, o Ministério da Saúde (MS) estabeleceu pela primeira vez a possibilidade de relação entre as crianças portadoras de microcefalia e a infecção congênita pelo vírus Zika, sendo confirmada pelo Instituto Evandro Chagas (IEC), laboratório de referência nacional e internacional em ciências biológicas, meio ambiente e medicina tropical das arboviroses. Objetivo: analisar as ações realizadas pelas enfermeiras na assistência às crianças com microcefalia relacionada ao Zika Vírus na Atenção Primária à Saúde. Metodologia: Trata-se de um estudo transversal, com abordagem qualitativa, realizado com enfermeiras que assistiram crianças com microcefalia por Zika Vírus em cinco municípios do NRS SUL/Itabuna. Os dados foram coletados por entrevista semiestruturada, entre agosto e setembro de 2020. A análise do perfil biopsicossocial das enfermeiras foi realizada por estatística descritiva e as entrevistas foram processadas pela análise de conteúdo temática proposta por Bardin. Principais Resultados: Revelou-se que, as ações de acompanhamento realizadas pelas enfermeiras se restringiram à imunização e ao Programa de Crescimento e Desenvolvimento, demonstrando a importância de um olhar ampliado para as complicações/sequelas da Zika nas crianças assistidas. Conclusão: Identificou-se que, a assistência de enfermagem é restritiva, sendo necessária ações de educação permanente para estas profissionais qualificarem o cuidado às crianças com microcefalia por Zika Vírus.

Introduction: Microcephaly is a neurological condition that is characterized by abnormalities in head growth and can be caused by several factors such as malnutrition, drug use, infections and, more recently, contamination by the Zika Virus. Only in 2015, the Ministry of Health (MS) established for the first time the possibility of a relationship between children with microcephaly and congenital Zika virus infection, which was confirmed by the Evandro Chagas Institute (IEC), a national and international reference laboratory in biological sciences, environment and tropical medicine of arboviruses. Objective: to analyze the actions performed by nurses in the care of children with microcephaly related to the Zika Virus in Primary Health Care. Methodology: This is a cross-sectional study, with a qualitative approach, carried out with nurses who assisted children with microcephaly due to Zika Virus in five municipalities of NRS SUL/Itabuna. Data were collected through semi-structured interviews, between August and September 2020. The analysis of the nurses' biopsychosocial profile was performed using descriptive statistics and the interviews were processed using the thematic content analysis proposed by Bardin. Main Results: It was revealed that the follow-up actions carried out by the nurses were restricted to immunization and the Growth and Development Program, demonstrating the importance of an expanded look at the complications/sequelae of Zika in the assisted children. Conclusion: It was identified that nursing care is restrictive, requiring continuing education actions for these professionals to qualify the care of children with microcephaly due to the Zika Virus.

Socioeconomic risk markers of leprosy in high-burden countries: A systematic review and meta-analysis.

Over 200,000 new cases of leprosy are detected each year, of which approximately 7% are associated with grade-2 disabilities (G2Ds). For achieving leprosy elimination, one of the main challenges will be targeting higher risk groups within endemic communities. Nevertheless, the socioeconomic risk markers of leprosy remain poorly understood. To address this gap we systematically reviewed MEDLINE/PubMed, Embase, LILACS and Web of Science for original articles investigating the social determinants of leprosy in countries with > 1000 cases/year in at least five years between 2006 and 2016. Cohort, case-control, cross-sectional, and ecological studies were eligible for inclusion; qualitative studies, case reports, and reviews were excluded. Out of 1,534 non-duplicate records, 96 full-text articles were reviewed, and 39 met inclusion criteria. 17 were included in random-effects meta-analyses for sex, occupation, food shortage, household contact, crowding, and lack of clean (i.e., treated) water. The majority of studies were conducted in Brazil, India, or Bangladesh while none were undertaken in low-income countries. Descriptive synthesis indicated that increased age, poor sanitary and socioeconomic conditions, lower level of education, and food-insecurity are risk markers for leprosy. Additionally, in pooled estimates, leprosy was associated with being male (RR = 1.33, 95% CI = 1.06-1.67), performing manual labor (RR = 2.15, 95% CI = 0.97-4.74), suffering from food shortage in the past (RR = 1.39, 95% CI = 1.05-1.85), being a household contact of a leprosy patient (RR = 3.40, 95% CI = 2.24-5.18), and living in a crowded household (≥5 per household) (RR = 1.38, 95% CI = 1.14-1.67). Lack of clean water did not appear to be a risk marker of leprosy (RR = 0.94, 95% CI = 0.65-1.35). Additionally, ecological studies provided evidence that lower inequality, better human development, increased healthcare coverage, and cash transfer programs are linked with lower leprosy risks. These findings point to a consistent relationship between leprosy and unfavorable economic circumstances and, thereby, underscore the pressing need of leprosy control policies to target socially vulnerable groups in high-burden countries.

Introdução: a análise espacial tem sido utilizada pela vigilância epidemiológica como estratégia para identificação de espaços urbanos sob maior risco de doenças. Nesse contexto, as ferramentas da informática em saúde podem auxiliar para a compreensão dos fenômenos envolvidos na difusão da dengue nos espaços de aglomeração populacional, elucidando questões relativas aos movimentos espaciais de sua ocorrência e subsidiando o delineamento de programas de combate a seu principal vetor. Objetivo: sintetizar e discutir as informações mais relevantes produzidas pelos estudos de análise espacial de dengue, as quais vêm contribuindo para ampliar o entendimento de sua dinâmica de transmissão, no propósito da aplicação na prática da vigilância epidemiológica. Método: trata-se de uma pesquisa de revisão integrativa de literatura, realizada com publicações de 1945 a 2017, na Web of Science sobre dengue, com uso dos descritores e operadores "Spatial Analysis" AND "Dengue" AND "Urban Area". Resultados: foram selecionados 35 artigos. O perfil das produções permitiu a identificação de sete assuntos mais abordados: mobilidade urbana, densidade populacional, fatores sociodemográficos, disponibilidade de água, temperatura, vegetação e urbanização. Considerações finais: a análise espacial, por meio dos Sistemas de Informação Geográfica, é uma ferramenta muito útil para o estudo das dinâmicas de transmissão da dengue, pois possibilita o conhecimento de áreas, períodos e fatores sociais e ambientais de maior risco, a fim de produzir alertas para os serviços de saúde

Introduction: The spatial analysis has been used by epidemiological surveillance as a strategy to identify urban spaces at greater risk of diseases. In this context, the tools of computer sciences apllied to health can help to understand the phenomena involved in the diffusion of dengue in areas of high population density. It clarifies the issues related to the spatial movements of dengue occurrence and subsidize the design of programs to combat its main vector. Objective: this study aimed to synthesize and discuss the most relevant information produced by the studies about spatial analysis of dengue, which have contributed to enlarge the understanding of its transmission dynamics, in the purpose of the practical application of epidemiological surveillance. Method: this is an integrative literature review carried out with publications from 1945 to 2017 in the Web of Science. The descriptors and boolean operators used were "Spatial Analysis" AND "Dengue" AND "Urban Area". Results: 35 papers were selected. The analysis of the productions allowed the identification of seven subjects: urban mobility, population density, sociodemographic factors, availability of water, temperature, vegetation and urbanization. Final considerations: the spatial analysis, through the Geographic Information Systems, is a very useful tool to the study of dengue transmission dynamics, because it allows the knowledge of areas, periods and social and environmental factors of greater risk, in order to produce alerts for health services.

Perfil dos pacientes renais crônicos em tratamento hemodialítico / Profile of chronic renal patients on renal dialysis treatment / Perfil de los pacientes con insuficiencia renal crónica en hemodiálisis

A insuficiência renal crônica é um problema de saúde pública devido ao aumento da incidência e mortalidade. Objetivou-se conhecer o perfil dos pacientes renais crônicos residentes em Itabuna em tratamento hemodialítico no ano de 2012. Tratou-se de um estudo transversal, que utilizou um ins-trumento de coleta para abordar aspectos socioeconômicos, tempo de tratamento, financiamento do tratamento e causa base da insuficiência. Foram incluídos 63 casos. Destes, 63,5% eram do sexo masculino, 52,3% brancos, com média de idade 49,8 anos, com ensino fundamental incompleto (34,9%) e 31,7% aposentados. A causa de base mais incidente foi hipertensão arterial (29,6%); 23,9% estavam em tratamento há dois anos, sendo 82,5% realizado pelo SUS. Concluiu-se, com base no perfil dos pacientes renais crônicos residentes em Itabuna, que a Hipertensão Arterial Sistêmica e o Diabetes Mellitus destacaram-se entre as causas base da doença renal crônica. Diante disso, é neces-sária maior atenção para a prevenção desses agravos, para evitar a evolução dos casos para a gravi-dade.

In Estrutural and Itapoã, fewer years of schooling, and in Itapoã and Varjão, lower income, were associated with RS. Cigarette smoking was associated with the presence of RS in all regions. The prevalence of RS in the three administrative regions investigated is consistent with that of other areas with a similar socioeconomic profile.

Perfil epidemiológico dos usuários dos Centros de Testagem e Aconselhamento do Estado de Santa Catarina, Brasil, no ano de 2005 / Epidemiological profile of the clientele in HIV Testing and Counseling Centers in Santa Catarina State, Brazil, 2005

Este estudo caracteriza o perfil dos usuários que procuraram os Centros de Testagem Anônima (CTAs) em Santa Catarina, Brasil, em 2005, e determina os fatores associados à contaminação pelo HIV. Foi realizado um estudo retrospectivo transversal em pessoas que freqüentaram os CTAs. Foram analisados os dados de 22.846 entrevistas realizadas no momento pré-teste, 64,7 por cento sexo feminino e 35,3 por cento masculino. A prevalência de HIV positivo encontrada nesses exames foi de 2 por cento no sexo feminino e 5,6 por cento no masculino. Utilizou-se análise bivariada e multivariada com regressão de Poisson. Os fatores de risco independentes para o contágio pelo DST/HIV no sexo feminino foram: faixa etária, estado civil, escolaridade, situação profissional, recorte populacional, risco do parceiro fixo, uso de preservativo e motivo para não usar preservativo com parceiro fixo. No sexo masculino foram: faixa etária, escolaridade, tipo de parceiro, recorte populacional, risco do parceiro, uso de preservativo e motivo para não usar preservativo com parceiro fixo. A soropositividade para homens e mulheres apresenta-se diferente, merecendo abordagens preventivas diferenciadas.

This study analyzes the user profile of HIV Testing and Counseling Centers in Santa Catarina State, Brazil, in 2005, and factors associated with HIV infection. The methodology employed a retrospective, cross-sectional study of individuals who attended Testing and Counseling Centers. Data from 22,846 interviews were analyzed (64.7 percent women and 35.3 percent men). HIV prevalence was 2.0 percent in women and 5.6 percent in men. Statistical analysis used bivariate and multivariate Poisson regression by gender. According to the Poisson regression, factors associated with HIV+ status were age bracket, schooling, marital status, professional situation, population group, steady partner's risk status, condom use, and reason for not using condoms with steady partner; for men, the independent variables were age bracket, schooling, type of partner, population group, steady partner's risk status, condom use, and reason for not using condoms with steady partner. HIV+ patterns differed between men and women, so that customized preventive approaches are needed.
