Viral hepatitis in female sex workers using the Respondent-Driven Sampling

OBJECTIVE To estimate the prevalence of hepatitis B virus and C virus infections and their genotypes and analyze the risk factors for the markers of exposure to hepatitis B virus in female sex workers in a region of intense sex trade. METHODS This is a cross-sectional study performed with four hundred and two female sex workers in Goiânia, Brazil. Data have been collected using the Respondent-Driven Sampling. The women have been interviewed and tested for markers of hepatitis B and C viruses. Positive samples have been genotyped. The data have been analyzed using the Respondent-Driven Sampling Analysis Tool, version 5.3, and Stata 11.0. RESULTS The adjusted prevalence for hepatitis B virus and C virus were 17.1% (95%CI 11.6–23.4) and 0.7% (95%CI 0.1–1.5), respectively. Only 28% (95%CI 21.1–36.4) of the participants had serological evidence of vaccination against hepatitis B virus. Being older (>; 40 years), being single, having a history of blood transfusion and use of cocaine, and ignoring the symptoms of sexually transmitted infections were associated with positivity for hepatitis B virus (p < 0.05). We have detected the subgenotype A1 of hepatitis B virus (n = 3) and the subtypes of hepatitis C virus 1a (n = 3) and 1b (n = 1). CONCLUSIONS We can observe a low prevalence of infection of hepatitis B and C viruses in the studied population. However, the findings of the analysis of the risk factors show the need for more investment in prevention programs for sexual and drug-related behavior, as well as more efforts to vaccinate this population against hepatitis B. The genotypes of the hepatitis B virus and C virus identified are consistent with those circulating in Brazil

Hepatitis A and E among immigrants and refugees in Central Brazil

OBJECTIVE To estimate the prevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) among immigrants and refugees in Goiás, Central Brazil. METHODS Overall, 355 individuals were interviewed, and blood samples were tested for anti-HAV and anti-HEV IgG. Anti-HEV-positive samples were similarly tested for HEV RNA. RESULTS All participants were from Latin American countries, most of whom, young adult males. The overall anti-HAV IgG prevalence was 87.4% (95%CI: 83.5–90.4), of whom 94.9%, 75.6%, and 60% were from Haiti, Venezuela, and other Latin American countries, respectively (p &lt; 0.001). Age above 19 years and more than 36 months residing in Brazil were associated with a higher prevalence of previous HAV and HEV infection, respectively. Of the children eligible for HAV vaccination according to the National Immunization Program, only eight (44%) had been vaccinated. The overall anti-HEV IgG prevalence was 6.5% (95%CI: 4.4–9.5). All anti-HEV IgG-positive individuals were Haitians, including a child born in Brazil. HEV RNA was detected in two of the anti-HEV IgG-positive samples. CONCLUSION The survey detected a high prevalence of anti-HAV and anti-HEV IgG among immigrants and refugees, and active HEV infection among some Haitian participants. Prevention measures are urgently required to interrupt enteric virus transmission in this emergent and vulnerable population

Factores asociados con infecciones de transmisión sexual en cortadores de caña de azúcar: contribuciones para el cuidado

Objective: to estimate the prevalence of Sexually Transmitted Infections (STIs) and associated factors in sugarcane cutters. Method: a cross-sectional, analytical study with 937 sugarcane cutters from Paraíba and Goiás, states of Brazil, respectively. An outcome variable was the positive results in some rapid tests for HIV, syphilis, hepatitis B and C. Bivariate and multiple analyses were performed to identify the association between these infections and sociodemographic and behavioral variables. Results: all participants were male, most were young adults and had low schooling. Prevalence of STI was estimated at 4.1% (95% CI: 3.0-5.5). According to multiple regression analysis, the variables age over 40 years (OR 5.0; CI 95%: 1.8-14), alcohol consumption (OR 3.9; CI 95%: 1.3-11.9), and illicit drugs (OR 2.9; CI 95%: 1.3-6.3) were factors associated with the STIs investigated. On the other hand, having some religion (OR 0.4; CI 95%: 0.2-0.8), and work in the Midwest Region (OR 0.4; CI 95%: 0.2-0.9) were factors negatively associated with these infections. Conclusion: presence of risk behaviors for STI among sugarcane cutters. Screening for these infections in groups of rural workers is essential for early diagnosis and breaking the chain of transmission.Objetivo: estimar la prevalencia de infecciones de transmisión sexual (ITS) y factores asociados en cortadores de caña de azúcar. Método: estudio analítico transversal con 937 cortadores de caña de azúcar de los estados de Paraíba y Goiás, en Brasil. Se consideró como variable el resultado positivo en algunas pruebas rápidas para VIH, sífilis, hepatitis B y C. Se realizaron análisis bivariados y múltiples para identificar una asociación entre estas infecciones y las variables sociodemográficas y de comportamiento. Resultados: todos los participantes eran hombres, la mayoría eran adultos jóvenes con bajo índice de escolaridad. Se estimó una prevalencia de ITS de 4.1% (IC 95%: 3.0-5.5). Según el análisis de regresión múltiple, variables como edad superior a 40 años (OR 5.0; IC 95%: 1.8-14), consumo de alcohol (OR 3.9; IC 95%: 1.3- 11.9) y drogas ilícitas (OR 2.9; IC 95%: 1.3-6.3) fueron factores asociados a las ITS investigadas. Por otro lado, factores como tener alguna religión (OR 0.4; IC 95%: 0.2-0.8) y trabajar en la región Centro-Oeste (OR 0.4; IC 95%: 0.2-0.9) tuvieron una asociación negativa en relación a estas infecciones. Conclusión: se advirtió la presencia de comportamientos de riesgo para ITS entre cortadores de caña de azúcar. La detección de estas infecciones en grupos de trabajadores rurales es esencial para la detección temprana de diagnóstico y para romper la cadena de transmisión.Objetivo: estimar a prevalência de Infecções Sexualmente Transmissíveis (IST) e fatores associados em cortadores de cana-de-açúcar. Método: estudo transversal, analítico, com 937 cortadores de cana-de-açúcar dos estados da Paraíba e de Goiás, no Brasil. Considerou-se como variável de desfecho a positividade em algum teste rápido para HIV, sífilis, hepatite B e C. Análises bivariada e múltipla foram realizadas para identificar associação entre essas infecções e variáveis sociodemográficas e comportamentais. Resultados: todos os participantes eram do sexo masculino, a maioria eram adultos jovens e possuíam baixa escolaridade. Estimou-se uma prevalência para IST de 4,1%(IC 95%: 3,0-5,5). De acordo com a análise de regressão múltipla, variáveis como idade acima de 40 anos (OR 5,0; IC 95%: 1,8-14), consumo de álcool (OR 3,9; IC 95%: 1,3-11,9) e de drogas ilícitas (OR 2,9; IC 95%: 1,3-6,3) foram fatores associados às IST investigadas. Por outro lado, ter alguma religião (OR 0,4; IC 95%: 0,2-0,8) e trabalhar na Região Centro-Oeste (OR 0,4; IC 95%: 0,2-0,9) foram fatores associados negativamente a essas infecções. Conclusão: presença de comportamentos de risco para as IST entre os cortadores de cana-de-açúcar. O rastreio destas infecções em grupos de trabalhadores rurais é fundamental para diagnóstico precoce e quebra da cadeia de transmissão

Alarming patterns of moderate and high-risk alcohol use among transgender women in Goiás, Central Brazil

BackgroundScant studies have examined alcohol consumption among transgender women in Latin America. This cross-sectional study estimated the prevalence and associated factors of risky alcohol use among transgender women in Goiás, a state located in the center of Brazil.MethodsParticipants were 440 transgender women (median age = 35 years, interquartile range = 9) recruited through respondent-driven sampling. All participants were interviewed about sociodemographic characteristics, violence, and risk behavior. Alcohol use was assessed using the alcohol use disorders identification test (AUDIT). An AUDIT score greater than or equal to eight was considered as risky alcohol consumption. Logistic regression analysis was used to examine predictors of risky alcohol use, and p-values &lt;0.05 were considered significant.ResultsThe majority were young, single, sex workers. Most transgender women had used alcohol in the previous year (85.7%), and more than half (56.6%) reported binge drinking and risky alcohol consumption (60.2%). There was a high overlap between sexual behavior, drugs, and alcohol use. Using alcohol during sex (adjusted odds ratio [aOR]: 2.9; 95% confidence interval [CI]: 1.7–4.8), cocaine/crack use (aOR: 2.3; 95% CI: 1.5–3.7) and having a drug user as a sexual partner (aOR: 2.9; 95% CI: 1.5–5.9) were independently associated with risky alcohol consumption.ConclusionAlcohol consumption was highly prevalent, and drugs seem to play an important role in risky alcohol consumption among transgender women Goiás. These findings support stakeholders to promote intervention strategies to reduce this pattern of alcohol consumption and reduce the burden of substance use disorders among transgender women

Fatores associados à utilização e reutilização de máscaras entre brasileiros durante a pandemia da COVID-19

Objetivo identificar os fatores associados à utilização e à reutilização de máscaras entre brasileiros durante a pandemia da COVID-19. Método estudo transversal desenvolvido nas cinco regiões brasileiras, entre adultos, via formulário eletrônico por meio de mídias sociais, contendo informações gerais e referentes à utilização de máscaras. Foram utilizadas análises bivariadas e regressões logísticas binárias para identificar fatores associados à utilização e à reutilização. Resultados participaram do estudo 3.981 (100%) pessoas. A utilização de máscaras totalizou 95,5%, (IC 95%: 94,8-96,1), com destaque para as de tecido (72,7%; IC 95%: 71,3-74,1) e as cirúrgicas (27,8%; IC 95%: 26,5-29,2). A porcentagem de reutilização foi de 71,1% (IC 95%: 69,7-72,5). A maioria (55,8%; IC 95%: 51,7-60,0) que usa, exclusivamente, máscara cirúrgica reutiliza-a. O sexo feminino e o contato prévio com pessoas com sintomas respiratórios aumentaram as chances de utilização (p≤0,001). Contudo, o sexo feminino diminuiu a possibilidade de reutilização da máscara cirúrgica (p≤0,001). Conclusão a quase totalidade dos participantes relatou utilizar máscaras, sendo mais recorrente a de tecido. Os achados chamam atenção para uma prática de risco, a reutilização da máscara cirúrgica e de papel. Diretrizes, políticas públicas e estratégias educativas são necessárias para o desenvolvimento de práticas assertivas no controle e prevenção da COVID-19.Objective to identify the factors associated with the use and reuse of masks among Brazilian individuals in the context of the COVID-19 pandemic. Method cross-sectional study conducted in the five Brazilian regions, among adult individuals, via an electronic form disseminated in social media, addressing general information and the use of masks. Bivariate analysis and binary logistic regression were used to identify the factors associated with the use and reuse of masks. Results 3,981 (100%) individuals participated in the study. In total, 95.5% (CI 95%: 94.8-96.1) reported using masks. Fabric masks were more frequently reported (72.7%; CI 95%: 71.3-74.1), followed by surgical masks (27.8%; CI 95%: 26.5-29.2). The percentage of reuse was 71.1% (CI 95%: 69.7-72.5). Most (55.8%; CI 95%: 51.7-60.0) of those exclusively wearing surgical masks reported its reuse. Being a woman and having had contact with individuals presenting respiratory symptoms increased the likelihood of wearing masks (p≤0.001). Additionally, being a woman decreased the likelihood of reusing surgical masks (p≤0.001). Conclusion virtually all the participants reported the use of masks, most frequently fabric masks. The findings draw attention to a risky practice, that of reusing surgical and paper masks. Therefore, guidelines, public policies, and educational strategies are needed to promote the correct use of masks to control and prevent COVID-19.Objetivo identificar los factores asociados con el uso y la reutilización de máscaras entre brasileños durante la pandemia del COVID-19. Método estudio transversal desarrollado en las cinco regiones brasileñas, entre adultos, aplicándose un formulario electrónico a través de las redes sociales, que contiene información general y relativo al uso de máscaras. Se utilizaron análisis bivariados y regresiones logísticas binarias para identificar los factores asociados con el uso y la reutilización. Resultados 3.981 (100%) personas participaron en el estudio. El uso de máscaras totalizó 95.5% (IC 95%: 94.8-96.1), particularmente las de tejido (72.7%; IC 95%: 71.3-74.1) y la quirúrgicas (27.8%; IC 95%: 26.5-29.2). El porcentaje de reutilización fue del 71,1% (IC 95%: 69,7-72,5). La mayoría (55.8%; IC 95%: 51.7-60.0) que usa exclusivamente una máscara quirúrgica la reutiliza. El género femenino y el contacto previo con personas con síntomas respiratorios aumentaron las posibilidades de uso (p≤0.001). Sin embargo, el sexo femenino disminuyó la posibilidad de reutilizar la máscara quirúrgica (p≤0.001). Conclusión casi todos los participantes informaron haber usado máscaras, siendo aquella de tejido más frecuente. Los hallazgos llaman la atención sobre una práctica arriesgada, la reutilización de la máscara quirúrgica y de papel. Las directrices, políticas públicas y estrategias educativas son necesarias para el desarrollo de prácticas asertivas en el control y la prevención del COVID-19

Human T-lymphotropic virus 1/2 infection among immigrants and refugees in Central Brazil, an emerging vulnerable population

IntroductionMigratory flows play a significant role in the spread of human T-lymphotropic virus 1/2 (HTLV-1/2). In the last decade, a substantial migration of individuals occurred from Haiti and Venezuela to Brazil. However, data on the prevalence of HTLV-1/2 infection among these international migrants in Brazil are scarce. This study describes the prevalence of this infection among immigrants and refugees in Central Brazil.MethodsA cross-sectional study was conducted with 537 international migrants in the State of Goiás, Central Brazil. Participants were interviewed, and blood samples were collected. Serological screening for anti-HTLV-1/2 was performed using an enzyme-linked immunosorbent assay (ELISA; Murex HTLV-I + II, DiaSorin, Dartford, UK), and seropositive samples were submitted for confirmation by a line immunoassay (INNO-LIA HTLV I/II, Fujirebio, Europe N.V., Belgium).ResultsThe majority of participants were males (54.4%), between 18 and 50 years old (78%; mean age: 29.1 years), self-declared black (55.1%), reported 1 to 12 years of formal education (70.9%), and were either Venezuelans (47.9%) or Haitians (39.7%). Additionally, 50.1% were immigrants, 49% were refugees, and five were Brazilian children (0.9%) born to Haitian immigrant parents. The overall prevalence of anti-HTLV-1/2 was 0.95% (95% CI: 0.31–2.28), with HTLV-1 at 0.19% and HTLV-2 at 0.76%. All seropositive individuals (n = 5) were refugees from Venezuela, resulting in a rate of 2.26% for anti-HTLV-1/2, HTLV-1 (0.45%) and HTLV-2 (1.81%) among Venezuelan refugees. Of the demographic and behavioral characteristics evaluated, unprotected sexual intercourse and having more than one sexual partner (≥2) in the previous 12 months were associated with HTLV-1/2 seropositivity among Venezuelans.ConclusionThis study revealed, despite the low seroprevalence of HTLV-1/2 among international migrants in Central Brazil, evidence of HTLV-1 and HTLV-2 infections in Venezuelan refugees. In addition, their characteristics highlight that specific social and health programs should be implemented for these emergent and socially vulnerable migrant groups
