Abstract
Of the 432 genital ulcer cases seen in 1985, 36 had donovanosis, thus forming an incidence of 8.33%. In contrast, 42 (6.38%) cases of donovanosis were diagnosed among a total of 658 cases of genital ulcers in 1983. The majority of patients in both epidemics were young unmarried men who contracted the disease through extramarital sexual intercourse. Perianal lesions were seen primarily in those who had a history of sodomy. The disease chiefly affected illiterate persons of low socioeconomic strata. The incubation period varied from 1 to 90 days. Twenty (62.50%) patients in the 1985 epidemic had an incubation period of less than 7 days, in contrast to only 9 (34.61%) in the 1983 epidemic. The epidemics occurred from autumn to the start of winter. Duration of the disease varied from 1 day to 6 years. The clinical features and sites of afflication were usual; however, pseudobubo and pseudoelephantiasis were conspicuous in a significant minority.
