HIV-1 INFECTION AND RELATED RISK FACTORS AMONG FEMALE SEX WORKERS IN URBAN AREAS OF ETHIOPIA

SUMMARY: A total of 6234 female sex workers practicing multi-partner sexual contacts (MPSC) from 23 urban areas of the country were tested for Human Immuno deficiency Virus type 1 (HIV1) infection, in 1988. The sample size ranged from 99 persons in Moyale, to 386 in Asmara. The mean age of the individuals studied was 24.2 years (ranging from 21.5 years to 27.1 years in the different towns). The HIV-1 prevalence rates varied from 1.3% (n=318) in Massawa, to 38.1% (n=312) in Dessie town; the mean for all towns being 17%. The highest prevalence rates were found in the towns along the road from Addis Ababa to Assab, in Bahr-Dar , Dessie and Mekele. The lowest prevalence rates were recorded in three towns of northern Ethiopia. This study indicated that Hiv-1 is widely spread in the urban areas of Ethiopia affecting female sex workers mainly in the 15-29 years age group. Previous episodes of other sexually transmitted diseases, and frequent change of sexual partners were identified as possible risk factors for HIV infection. Frequent mobility of these females may have played a significant role in HIV transmission between the towns

HIV -1 INFECTION AND SOME RELATED RISK FACTORS AMONG FEMALE SEX WORKERS IN ADDIS ABABA

SUMMARY: A sero-epidemiological survey on HIV-l infection was carried out in July 1989, among four groups of female sex workers randomly selected in Addis Ababa. The four groups were comprised of: bar girls, tej (traditional wine) sellers, tella (traditional beer) sellers and females in red light houses. Sera were tested by ELISA and confirmed y western blot. The mean age of the 2617 females studied was 31.2 years, and the prevalence rate for HIV-1 was 24.7%. Persons in the 15-24 age group were affected more frequently. The highest prevalence (43.8%) was found among the females in red light houses. Females with relatively larger number of sexual partners and those who had previous exposure to STDs, had a higher prevalence of the infection. The survey revealed that HIV-1 is highly prevalent among females practicing multi-partner sexual contact (MPSC) in Addis Ababa, and the infection concentrates in the central areas of the city
