Abstract
A cross-sectional serosurvey was conducted to assess the proportion of persons exposed to hantaviruses in a virus-endemic area of the state of Minas Gerais, Brazil. Findings of this study suggested the presence of >1 hantaviruses circulating in this region causing hantavirus pulmonary syndrome, mild disease, or asymptomatic infection.

In Brazil, >1,080 cases of hantavirus pulmonary syndrome (HPS) have been confirmed since 1993 (case-fatality rate 40%). More HPS cases (209) are reported in the state of Minas Gerais than in any other state in Brazil (M.L. Nunes, pers. comm.). In Minas Gerais, molecular studies identified a hantavirus called Araraquara virus associated with HPS cases. The wild rodent Necromys lasiurus (the hairy-tailed bolo mouse, also named Bolomys lasiurus) was implicated as a reservoir of this virus (1). Because asymptomatic infection with hantaviruses also has been detected in Minas Gerais, we conducted a cross-sectional survey to assess the proportion of persons exposed to hantaviruses and to identify associated risk factors.
