Lessons from the Covid-19 pandemic
This study aimed to estimate the prevalence and identify social factors and preventive strategies associated with the coronavirus disease 2019 (COVID-19) in socio and economically vulnerable people (recyclable waste pikers, immigrants/refugees, and homeless people) in Goiânia, Goiás State, Central-Western Brazil. A cross-sectional study was conducted from July 2020 to October 2020. COVID-19 positivity was defined as a positive total anti-SARS-COV…
Seroprevalence of antibodies against herpesvirus type 2 in a female prison population in Mato Grosso
The objective of this text is to describe the seroprevalence of antibodies against herpes simplex virus 2 in inmates of a female public prison in Mato Grosso. This is a cross-sectional study carried out with biobank data from a survey carried out with women deprived of liberty in a female penitentiary in Tangará da Serra - MT. Data collection was carried out through interviews with 50 women. To determine the seroprevalence of HSV-2 infection, ser…
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…
Evaluation of HBV-Like Circulation in Wild and Farm Animals from Brazil and Uruguay
The origin of the hepatitis B virus is a subject of wide deliberation among researchers. As a result, increasing academic interest has focused on the spread of the virus in different animal species. However, the sources of viral infection for many of these animals are unknown since transmission may occur from animal to animal, human to human, animal to human, and human to animal. The aim of this study was to evaluate hepadnavirus circulation in w…
A Cross-Sectional Study of Viral Hepatitis Perception among Residents from Southeast and North Regions of Brazil
Few data are available regarding viral hepatitis perception among the general global population. The present study aims to estimate the perception of viral hepatitis in a cohort of individuals living in two geographical regions of Brazil: North (Manaus city (MA)) and Southeast (Rio de Janeiro city (RJ)). A cross-sectional, descriptive study was carried out among 287 subjects recruited in MA (134) and RJ (153). All individuals answered a questionn…
Cross-Sectional Study to Determine the Prevalence of Hepatitis B and C Virus Infection in High Risk Groups in the Northeast Region of Brazil
Background : HBV (Hepatitis B Virus) and HCV (Hepatitis C Virus) infections are more prevalent in vulnerable populations than the general population. The objective of this study was to investigate the prevalence of HBV and HCV infection in HIV-positive patients (GI), chronic renal failure (CRF) patients (GII) and coagulation disorder individuals (GIII). Methods : A cross-sectional study was conducted from June 2014 to March 2015. Serum samples we…
A Cross Section Study to Determine the Prevalence of Antibodies against HIV Infection among Hepatitis B and C Infected Individuals
(1) BACKGROUND: There are limited data regarding human immunodeficiency virus (HIV) prevalence among hepatitis B virus (HBV) or hepatitis C virus (HCV) infected individuals. The aim of this cross-sectional study is to determine the prevalence of HBV and HCV infection among HIV individuals; (2) METHODS: A total of 409 patients (126 HBV+ and 283 HCV+) referred to the Brazilian Reference Laboratory for Viral Hepatitis from 2010 to 2013 donated serum…
Cross-Sectional Study of Hepatitis A Virus Infection in the Pantanal Population before Vaccine Implementation in Brazil
Population-based prevalence studies are essential tools for screening of hepatitis A and provide important data on susceptible groups. However, surveillance in isolated communities is difficult because of the limited access to these areas and the need for blood sample collection. This study aimed to determine the anti-HAV prevalence using oral fluid samples to provide an alternative tool for epidemiological studies that might be useful for vaccin…
Key drug use, health and socio-economic characteristics of young crack users in two Brazilian cities
Crack users in the two Brazilian sites featured extensive socio-economic marginalization, crack and poly-drug use as well as sexual risk behaviours, and compromised health status. Social and health service utilization are low, yet needs are high. There is an urgent need for further research and for targeted interventions for crack use in Brazil
