[Leptospirosis. Serological study of an epidemic outbrake in the province of Camagüey].

A brief historical review of human leptospirosis up to 1972 in Cuba is made. Serological studies were made among sugar cane workers from the Army of Working Youth (EJT) during an epidemic leptospirosis outbreak at the Camgüey province in 1973. Results of those studies are presented. The outbreak was due to several serotypes of Leptospira. Other works of the author as well as several reports obtained from specialized medical literature are compared.
