    Snippet: Pellizzer et al. 36 performed a sero-epidemiological study to evaluate the risk of leptospirosis in a population in Northeast Italy exposed to a severe flood event. This area is endemic for leptospirosis and exhibits and average of 4 cases/100,000 inhabitants. Seven out of 44 subjects exposed to floodwaters exhibited anti-Leptospira specific IgM antibodies and five were confirmed positive by micro-agglutination test. Re-testing a few months later.....
    Document: Pellizzer et al. 36 performed a sero-epidemiological study to evaluate the risk of leptospirosis in a population in Northeast Italy exposed to a severe flood event. This area is endemic for leptospirosis and exhibits and average of 4 cases/100,000 inhabitants. Seven out of 44 subjects exposed to floodwaters exhibited anti-Leptospira specific IgM antibodies and five were confirmed positive by micro-agglutination test. Re-testing a few months later found significant antibody titers greater than 100 against serovar Copenhangeni in three cases (6.8% seroconversion rate). Overall, the rate for seroconversion for leptospirosis appeared to be low, and while flooding appeared to be the sole risk factor, confirmation was not possible due to a lack of a control group.
