[Human leptospirosis in Martinique].

Eco-geographic conditions are good for spread of Leptospiroses in Martinique. Leptospiroses are widespread in all parts of the Island. Many people have animals in inhabitation area. When they are sought, Leptospiroses can be diagnosed. During 3 years, we found many cases confirmed by biological diagnosis (immunological research of antibodies). Icterohaemorrhagiae is the first serogroup encountered and the most frequent. After follow Canicola, Ballum, Cynopteri and Javanica. Actually, Leptospiroses are a disease more frequent than is generally thought in Martinique. But only the severe cases are hospitalized, so diagnosed. Many cases of fever of unknown origin can be Leptospiroses.
