Abstract
INTRODUCTION
Leptospirosis is caused by a bacterium of the genus Leptospira. This study aimed at investigating the seroprevalence of and risk factors for leptospirosis in humans in Manaus, State of Amazonas.
METHODS
Interviews were performed, and 1,000 blood serum samples were examined using a microscopic agglutination test.
RESULTS
Forty-three cases were positive; there were 10 serotypes, with coagglutination in 8 cases. The most frequently occurring serotypes were Icterohaemorrhagiae (20.7%), Cynopteri (20.7%), Australis (18.8%), and Copenhageni (16.9%), and the Midwest (54.7%) and South (23.8%) had the most cases; these areas lack basic sanitation.
CONCLUSIONS
Disease occurrence might be reduced through improved basic infrastructural conditions.
