Socioecology and Prevalence of Sars‐CoV‐2 Infection in Quilombolas Living in the Brazilian Amazon
OBJECTIVES: This cross-sectional study presents socioecological, epidemiological aspects, and the seroprevalence of immunoglobulin G (IgG) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a group of quilombola (afro-derived) communities in the states of Pará and Tocantins, in the Brazilian Amazon, to evaluate the impact of SARS-CoV-2 prevalence among them. METHODS: A total of 551 individuals participated. The detection of a…
First report on human T-lymphotropic virus 1 infection in a group of transgender women
Introduction: There is a lack of data on human T-lymphotropic virus 1 (HTLV-1) infection among transgender women (TGW). Therefore, this study estimated the prevalence of HTLV-1 infection in a group of TGW in Brazil. Methods: A cross-sectional study was conducted with 235 TGW in Goiânia City, Central Brazil. Respondent-driven sampling was used for recruitment. All participants were interviewed, and serum samples were tested for anti-HTLV-1/2 using…
Prevalence and Risk Factors for HTLV-1/2 Infection in Quilombo Remnant Communities Living in the Brazilian Amazon
Human T-lymphotropic viruses 1 and 2 (HTLV-1 and HTLV-2) are retroviruses that originated on the African continent and dispersed throughout other continents through human migratory flows. This study describes the prevalence of HTLV-1 and HTLV-2 infection in residents of 11 quilombo remnant communities in the state of Pará, Brazil, and the associated risk factors. A total of 859 individuals (334 men and 525 women), aged between 7 and 91 years, par…
Prevalence of High Risk HPV in HIV-Infected Women From Belém, Pará, Amazon Region of Brazil: A Cross-Sectional Study
Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in B…
High prevalence of anti-Sars-CoV-2 IgG antibody in the Xikrin of Bacajá (Kayapó) indigenous population in the brazilian Amazon
The COVID-19 pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) reached the Brazilian Amazon and spread among indigenous populations. In the present study, we demonstrate a high prevalence of infection among the Xikrin of Bacajá people (Kayapó). A sample of 100 individuals of both sexes (51 men and 49 women) with ages ranging from 2 to 82 years were clinically evaluated and tested for the presence of anti-SARS-CoV-2 I…
Migration in times of pandemic: Sars-CoV-2 infection among the Warao indigenous refugees in Belém, Pará, Amazonia, Brazil
Epidemiological aspects of retrovirus (HTLV) infection among Indian populations in the Amazon Region of Brazil
HTLV was initially described in association with a form of leukemia in Japan and a neurological disease in the Caribbean. It was soon shown that HTLV-II was endemic among Amerindians and particularly among Brazilian Indians. The Amazon Region of Brazil is presently the largest endemic area for this virus and has allowed several studies concerning virus biology, the search for overt disease, epidemiological data including detailed demographic data…
