Leptospirosis seroprevalence and exposure factors in three informal settlements of French Guiana: An opportunistic survey.

ABSTRACT:

Background

Leptospirosis is a zoonotic disease of increasing importance in French Guiana. It particularly affects subjects living in precarious conditions. We aimed to determine the seroprevalence and the risk of exposure to leptospirosis among inhabitants of three informal settlements in French Guiana.

Methods

A serological investigation was conducted in 2022 in three informal settlements in the area of Cayenne, the main city of French Guiana. Leptospirosis exposure factors were assessed in volunteers aged > 15 through a standardized questionnaire. Leptospirosis seroprevalence was evaluated with Microscopic Agglutination Test (MAT) using 17 pathogenic Leptospira antigens with a reactivity threshold of 1:100.

Results

In 266 participants, median [IQR] age was 42 [34-52
