[A clinico-epidemiological study of leptospirosis in adults in the province of Ciego de Avila].

A clinical epidemiological study of reported leptospirosis cases in adults in the period 1984-1988 in the province Ciego de Avila, Republic of Cuba, was conducted. The most frequent symptoms and signs were: fever, headache and arthralgia. Eighty-two percent of patient were anicteric. The most frequent presumptive diagnosis included leptospirosis, virosis, and febrile syndrome. Sporadic cases predominated over cluster cases. The incidence of cases was higher from October to December. Sixty-five percent of patients were 36 years old or less. The serogroups detected more frequently were Leptospira interrogans var. Australia and Leptospira interrogans var Pomona. The high range of diagnostic and presumptive approaches with cases show that most cases would go undetected if an active surveillance is not implemented.
