Abstract

Objective analyze serological profile and spatial distribution of Mycobacterium leprae infection and disease.Methods cross-sectional study with cases of leprosy (n=42), household contacts (n=81) and school contacts (n=358). Interviews, dermato-neurological examination, serological and georeferencing made.Results all seropositive cases lived in rural areas, more than two people per household, 50.0% had alteration of foot strength. 75.0% were elderly and married participants. Among seropositive schoolchildren, 75.0% female, 69.4% lived with more than four people 80.6% slept in the bedroom with someone. It was possible to observe hyper endemic areas of cases in the studied municipality and spatial-temporal relation among them (p=0.010). In addition, concentration of cases and schoolchildren in sectors of lower family income per capita was found.Conclusion the serological analysis revealed that the cohabitation condition was related to the Mycobacterium leprae infection, and the spatial analysis showed a hidden endemic scenario.
