Abstract

INTRODUCTION: Rodent-borne hantaviruses cause severe human diseases. We completed a serological survey of hantavirus infection in rural inhabitants of Turvo County, in the southern State of Santa Catarina, Brazil, in which seropositivity for hantavirus was correlated to previous disease in the participants. METHODS: The levels of IgG antibodies to hantavirus Araraquara in the sera of 257 individuals were determined using an immunoenzymatic assay. RESULTS: IgG antibodies to hantavirus were found in 2.3% of the participants. All seropositive participants reported previous disease with symptoms suggestive of hantavirus cardiopulmonary syndrome. CONCLUSIONS: Human infections causing unreported cardiopulmonary syndrome probably occur in the southern State of Santa Catarina.INTRODUÇÃO: Hantaviroses são zoonoses de roedores silvestres que causam doenças graves em seres humanos. Este trabalho mostra inquérito sorológico para hantavírus em população rural e periurbana do município de Turvo, Estado de Santa Catarina e a correlação da presença de anticorpos anti-hantavírus com a história mórbida pregressa dos indivíduos. MÉTODOS: Investigaram-se os 257 participantes do estudo quanto à presença de anticorpos IgG séricos anti-hantavírus Araraquara, por método imunoenzimático. RESULTADOS: A prevalência de anticorpos anti-hantavírus na população foi de 2,3%. Os soropositivos possuíam antecedente nosológico sugestivo de hantavirose pregressa. CONCLUSÕES: Os achados mostram a ocorrência de infecções por hantavírus no extremo sul de Santa Catarina.
