To identify factors associated with disease severity, we examined 102 patients with quantitative PCR-confirmed leptospirosis in Martinique during 2010-2013. Associated factors were hypotension, chest auscultation abnormalities, icterus, oligo/anuria, thrombocytopenia, prothrombin time <68%, high levels of leptospiremia, and infection with L. interrogans serovar Icterohaemorrhagiae/Copenhageni.
