Abstract
During the 3 mo. between Dec. 1979 and Feb. 1980, 2867 patients attended a sexually transmitted diseases clinic. Of the 929 (23.4%) patients examined and interviewed, clinical and laboratory findings showed that chancroid was the most common disease (38.4%) and gonorrhea almost as common (35.3%) in men. Pelvic inflammatory disease was the most common disease (47.0%) and gonorrhoea the next least common (22.7%) in women.
