Abstract
In Brazil, the first confirmed cases of hantavirus cardiopulmonary syndrome in Indigenous
populations occurred in 2001. The purpose of this study was to determine the seroprevalence of
orthohantavirus infections in the Utiariti Indigenous land located in the southeastern region of the
Brazilian Amazon. In December 2014 and 2015, a survey was conducted using an enzyme-linked
immunosorbent assay in nine villages belonging to the Haliti–Paresí Indigenous communities. A
total of 301 participants were enrolled in the study. Of the two study cohorts, the one from 2014
showed a prevalence of 12.4%, whereas the one from 2015 had a serum prevalence of 13.4%. Analysis
of the paired samples of 110 Indigenous people who participated in both stages of the study enabled
identification of four individuals who had seroconverted during the study period. Identifying the
circulation of orthohantaviruses in the Utiariti Indigenous land highlights a serious public health
problem in viral expansion and highlights the need to implement preventive measures appropriate
to the sociocultural reality of these communities.
