@entity1526 @entity1 @entity66
INTRODUCTION: @entity1526 is not considered an @entity66 in the State of Maranh  o. However, entomological surveys showed high natural vector infection indices and acute cases have been identified in the last few decades. This study aimed to analyze the social, demographic and environmental conditions involved in transmission. METHODS: The study describes acute @entity1526 identified from 1994 to 2008. Information regarding the cases was obtained from the Information System for @entity66 (Sinan), National Health Foundation (Funasa) database and medical records. Entomological surveys were conducted from 2002. RESULTS: Data analysis identified 32 cases from 17 municipal districts, with 84.4% of @entity1 from rural areas. The disease was more frequent in @entity1 (67%). The most frequent occupation was student, 38.9% of cases, followed by farmer and hunter, 27.8%. CONCLUSIONS: The study suggests that transmission was vectorial and occurred in the wild or peridomicile.
