COVID-19 em crianças, adolescentes e jovens: estudo transversal no Espírito Santo, 2020

Objective: To Analyze self-reported sociodemographic and clinical aspects among individuals aged 2 to 22 years and possible associations with SARS-CoV-2 infection in Espírito Santo. Methods: Serial cross-sectional population-based study carried out from May to June 2020. The percentage of positivity for COVID-19 was evaluated by serological test, and the associated factors by Pearson's chi-square test (significance level of 5%). Results: Among 1,693 individuals aged 2 to 22 years, 6,1% tested positive for COVID-19 and, among these, 35.5% did not present any symptoms. Differences were identified between positive and negative regarding the number of symptoms (p-value=0.001). Cough was reported by 40.4% of positive individuals. Only 14.3% sought health care, with 29.8% among the positive and 13.3% among the negative (p-value=0.001). Conclusion: The percentage of asymptomatic patients can impact the transmission chain of COVID-19 in schools and boost outbreaks of the disease in schools.Objetivo: Analisar aspectos sociodemográficos e clínicos autorreferidos entre indivíduos de 2 a 22 anos de idade e possíveis associações com infecção por SARS-CoV-2 no Espírito Santo, Brasil. Métodos: Estudo transversal seriado de base populacional, realizado de maio a junho de 2020. Avaliou-se o percentual de positividade para COVID-19, por teste sorológico, e os fatores associados pelo teste qui-quadrado de Pearson (nível de significância de 5%). Resultados: Entre 1.693 indivíduos de 2 a 22 anos, 6,1% apresentaram teste positivo para COVID-19; destes, 35,5% não apresentaram nenhum sintoma. Identificou-se diferenças entre os soropositivos e soronegativos quanto ao número de sintomas (p-valor=0,001). A tosse foi relatada por 40,4% dos indivíduos soropositivos. Apenas 14,3% procuraram unidades de saúde, sendo 29,8% entre os soropositivos e 13,3% entre os soronegativos (p-valor=0,001). Conclusão: O percentual de indivíduos assintomáticos pode impactar a cadeia de transmissão da COVID-19 nas escolas, e impulsionar surtos da doença no mesmo ambiente escolar

Fatores associados ao tipo de reação hansênica: um estudo caso controle / Factors associated with the type of hansenic reaction: a case control study

Objetivo: analisar fatores associados ao tipo de reação hansênica no Espírito Santo. Método: estudo caso controle com indivíduos notificados por hanseníase no Sistema de Informação de Agravos de Notificação entre 2008 e 2017 e que tiveram reação hansênica durante o tratamento. Foi considerado caso aquele que desenvolveu reação tipo 2 e controle, do tipo 1. Calculou-se OddsRatio e OddsRatio Ajustada. Resultados: Foram incluídos 1.363 indivíduos, 21,3% com reação do tipo 2 e 78,7%, do tipo 1. Pacientes com reação tipo 2 tiveram mais chance de não serem de raça branca, residirem em um município de IDH médio e serem multibacilares. Conclusões: condições sociais influenciam o tipo reacional, porém, não há evidências quanto a fatores raciais. Entender e considerar esses fatores podem contribuir com a adesão ao tratamento da hanseníase no Brasil

Covid-19 em áreas de aglomerados subnormais e não subnormais no Espírito Santo, Brasil

Objectives: to estimate the prevalence of SARS-CoV-2 infection in residents of the Greater Vitória region living in subnormal and non-subnormal agglomerations; and, compare sociodemographic and clinical characteristics of total residents (infected and not infected with SARS-CoV-2), among these clusters. Method: Population-based prevalence study, through serological testing carried out in 2020, with a study unit in households in Greater Vitória, grouped into census tracts classified as sub-normal clusters (AGSN) and non-sub-normal clusters (AGNSN ). The two groups were compared in terms of prevalence and associated factors. The significance level adopted was 5%. Results: The prevalence found in the AGSN was 12.05% (95% CI from 9.59 to 14.50%), and in the AGNSN group it was 10.23% (95% CI from 7.97% to 12.50% ) this difference was not statistically significant (p = 0.273). Comparing the sociodemographic characteristics, more people who declare themselves to be of mixed race were found in the SGNA, a higher percentage of illiterates and people with only elementary education, greater number of residents per household, longer stay in public transport, sharing a bathroom with another household , fewer bedrooms per residence and higher frequency of irregular water supply when compared to AGNSN(P<0.05). Conclusions: The epidemiological characteristics of the SNGA residents show the social inequalities that can hinder control measures in a pandemic situation.Objetivos: estimar prevalência de infecção pelo SARS-CoV-2 em residentes na região da Grande Vitória moradores de aglomerados subnormais e não subnormais; e, comparar características sociodemográficas e clínicas dos residentes totais (infectados e não infectados com o SARS-CoV-2), entre esses aglomerados.  Método: Estudo de prevalência de base populacional, por meio de teste sorológico realizado em 2020, com unidade de estudo em domicílios da Grande Vitória, agrupados em setores censitários classificados como Aglomerados sub-normais (AGSN) e os Aglomerados não sub-normais (AGNSN). Os dois grupos foram comparados quanto a prevalência e fatores associados. O nível de significância adotado foi de 5%. Resultados: A prevalência encontrada no AGSN foi 12,05% (IC 95% de 9,59 a 14,50%), e no grupo AGNSN foi 10,23% (IC 95% de 7,97% a 12,50%) esta diferença não foi estatisticamente significante (p = 0,273). Comparando-se as características sociodemográficas foram encontradas nos AGSN mais pessoas que se autodeclaram da raça cor parda, percentual maior de analfabetos e pessoas apenas com ensino fundamental, maior número de moradores por domicílio, maior permanência em transporte coletivo, compartilhamento de banheiro com outro domicílio, menos dormitórios por residência e maior frequência de abastecimento irregular de água quando comparadas aos AGNSN(P<0,05). Conclusões: As características epidemiológicas dos moradores de AGSN evidenciam as desigualdades sociais que podem dificultar as medidas de controle em uma situação de pandemia

Yellow fever outbreak in a rural-urban mixed community of Espírito Santo, Brazil: epidemiological aspects

Objective. To describe the epidemiological aspects of an outbreak of yellow fever (YF) that occurred in the state of Espírito Santo, Brazil, from 1 January 2017 – 31 July 2017. Methods. A descriptive, quantitative, retrospective approach analyzed secondary data obtained from the national notification systems, Information System of Diseases Notifications (SINAN), Laboratory Environment Manager (GAL), and the Espírito Santo Health Secretariat (SESA). Results. From 1 January 2017 – 8 July 2017, a total of 824 cases were reported in Espírito Santo, 307 (37%) of which were confirmed as YF. Of these, 95 (30.9%) died from the disease. Men were those most affected, corresponding to 244 (79.5%) cases, and women to 63 (20.5%) cases. The greatest incidence rate registered was in the city of Santa Leopoldina (380.2 cases/100 000 inhabitants). The outbreak evolved rapidly and a response was possible due to a multidisciplinary group created specifically to tackle the YF outbreak. Conclusions. The data were received and analyzed quickly and the response, consisting of immediate treatment of the cases and a blocking vaccination strategy, was developed to halt the progression of this fatal disease. In spite of these efforts, the case fatality rate of yellow fever remained high

One brain sample was positive for WNV by RT-qPCR and the virus was isolated in C6/36 cell culture and sequenced. We obtained a nearly complete genome of WNV co-infected with Peruvian horse sickness virus (PHSV) in the cell culture. After confirmation of PHSV by next-generation sequencing, a new PHSV RT-qPCR protocol was developed, which was used to detect another horse positive only for PHSV. This assay provides a simple and direct method for easy identification of PHSV from biological samples from horses and may become a useful tool in the epidemiological surveillance of this virus. It is the first case of PHSV in Brazil, and only the third country overall to report, 23 years after the first confirmed notification in Peru. Moreover, it is the first reported co-infection of PHSV and WNV in a horse with neurological signs, confirmed by RT-qPCR

First isolation of West Nile virus in Brazil

BACKGROUND Serological evidence of West Nile virus (WNV) infection has been reported in different regions of Brazil from equine and human hosts but the virus had never been isolated in the country. OBJECTIVES We sought to identify the viral etiology of equine encephalitis in Espírito Santo state. METHODS We performed viral culture in C6/36 cells, molecular detection of WNV genome, histopathology and immunohistochemistry from horse cerebral tissue. We also carried out sequencing, phylogenetic analysis and molecular clock. FINDINGS Histopathologic analysis from horse cerebral tissue showed injury related to encephalitis and WNV infection was confirmed by immunohistochemistry. The virus was detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) from brain tissue and subsequently isolated in C6/36 cells. WNV full-length genome was sequenced showing the isolated strain belongs to lineage 1a. The molecular clock indicated that Brazilian WNV strain share the same common ancestor that were circulating in US during 2002-2005. MAIN CONCLUSIONS Here we report the first isolation of WNV in Brazil from a horse with neurologic disease, which was clustered into lineage 1a with others US WNV strains isolated in beginning of 2000’s decade
