Answer

Leptospirosis, as a clinical entity, is underdiagnosed and underreported. From 1985-1994, the reported annual incidence ranged from 0.02-0.04 cases per 100,000 persons. In 1994, 38 leptospirosis cases were reported nationwide, and the Council of State and Territorial Epidemiologists recommended removing leptospirosis from the list of notifiable diseases. [23]
