Leptospirosis is a zoonotic infection induced by pathogen bacteria (genus: Leptospira) growing in water polluted by animal fluids. Due to its 10 fold occurence in French overseas aera, and especially in Reunion Island, as compared to metropoly, it is considered as a major public health issue. An important inter-individual variability in humoral immune response suggests that vaccination should be recommended in exposed subjects. This cohort study aimed to determine if subjects that have been infected by leptospirosis for 1 to 7 years still remain immunized, and then do not need vaccination.
