HTLV-1/2 in Indigenous Peoples of the Brazilian Amazon: Seroprevalence, Molecular Characterization and Sociobehavioral Factors Related to Risk of Infection.
Viruses
December 2022
HTLV-1/2 infection is endemic in Indigenous peoples of the Americas. Its origin is attributed to the migratory flow of Amerindian ancestral peoples. The present study aimed to investigate the seroprevalence of HTLV-1/2 infection in Indigenous peoples of the Brazilian Amazon.

Article Synopsis
- * Out of 907 participants, the study found an overall prevalence of 0.8% for HTLV-1/2, with slightly higher rates in men (0.9%) compared to women (0.7%).
- * The findings highlighted risky behaviors among seropositive patients, such as a lack of condom use, and called for improved public health policies to prevent HTLV spread in these communities with limited access to healthcare.

In Brazil, the coronavirus disease 2019 (COVID-19) epidemic spread rapidly in a heterogeneous way, mainly due to the different socioeconomic and behavioral characteristics of different regional populations and different evaluation periods. We performed a cross-sectional study including 1,337 individuals (first wave = 736/second wave = 601) after the first two waves of COVID-19 in the city of Belém, the capital of the state of Pará. The detection of IgG anti-SARS-CoV-2 antibodies was performed using an enzyme-linked immunosorbent assay test followed by statistical analysis using the RStudio program.

Our results showed a high seroprevalence (39.24%) of anti-SARS-CoV-2 IgG antibodies among the population of the capital of the state of Pará after the first wave of the pandemic.

Article Synopsis
- Human T-lymphotropic viruses 1 and 2 (HTLV-1 and HTLV-2) are retroviruses that spread from Africa and were investigated in 11 quilombo communities in Pará, Brazil.
- The study involved 859 participants, with blood tests conducted to assess the prevalence of HTLV infections, revealing that only four individuals were seropositive (one for HTLV-1 and three for HTLV-2).
- The only identified risk factor for HTLV infection was blood transfusion, highlighting the need for ongoing research and public health strategies to manage this viral spread in these communities.
