Objective: Description of the epidemiology of HIV infection among sex worke
rs (SW) in Accra, Ghana.
Methods: In all, 1013 SW working out of their homes (seaters) or finding cu
stomers in bars, hotels, brothels or on the street (roamers) were interview
ed and tested for HIV.
Results: Overall, prevalence of HIV infection was nearly 50% (506 of 1013),
varying from 26% (133 of 507) among the roamers to 74% (368 of 496) among
the sealers. Profound differences were noted between these two categories o
f SW with regard to age, number of clients per day, price per instance of i
ntercourse, condom use, and other characteristics. Respectively, 27% and 58
% of roamers and seaters were infected with HIV within their first 6 months
of sex work, despite a limited number of unprotected sex acts with seropos
itive clients. Independent risk factors fur HIV infection varied between ty
pes of SW: age among the roamers; region of origin and duration of sex work
among the sealers; number of clients per day, and presence of current or p
ast genital ulcer and gonococcal cervicitis in both groups.
Conclusion: In Accra, considerable heterogeneity exists in the population o
f SWs. In both categories of SW, new recruits become rapidly infected with
HIV after entering the trade. The 25-fold higher prevalence of HIV among SW
s than in the general adult population suggests that in Accra, as in many c
ities of West Africa, a high fraction of new cases of HIV infection continu
e to be acquired from SWs. Intervention programs targeting SW should be an
essential component of national AIDS control strategies. Special efforts sh
ould be made to identify and offer preventive services to new sex workers.
