[Epidemiological study on sexually transmitted diseases in Saitama Prefecture--mainly study of male urethritis].
Epidemiological studies on sexually transmitted diseases (STDs) in Saitama Prefecture, from 1989 through 1991, were performed and the following results were obtained. The number of patients was 1,833 (male: 1,532, female: 30) cases in 1989, 1,294 (male: 1,163, female: 131) cases in 1990, and 1,672 (male: 1,478, female: 149) cases in 1991. Male patients in their twenties or thirties were often affected by STDs. The order of frequency of STDs was roughly as follows; non-gonococcal and non-chlamydial urethritis, gonococcal urethritis, chlamydial rethritis, condyloma acuminatum, genital herpeic infection and syphilis. Concerning the criteria of the diagnosis on chlamydial urethritis, cases diagnosed by only clinical findings decreased markedly from 1989 through 1991, cases diagnosed by the combination of the antibody of C. trachomatis and clinical findings increased, and cases diagnosed by the detection of C. trachomatis were always about 70%. Male patients were mostly infected from prostitutes. Many patients with STDs were often infected in Taiwan, the Philippines, the Kingdom of Thailand and Republic of Korea.
