Human immunodeficiency virus type 1 (HIV-1) infection among female prostitutes in Borno State of Nigeria: one year follow-up.

Serological investigations on female prostitutes resident in Borno State in northeastern Nigeria have shown that the seroprevalence of HIV-1 infection has increased 9.81%--fold in one year. The highest sero-prevalence rates were found amongst prostitutes who had not benefited from previous health education campaigns. Prostitution appears to be on the increase in spite of AIDS probably because of the difficulty in finding alternative means of making a living. Attempts to halt the spread of HIV infection are hampered by the fact that most prostitutes are indifferent to the use of condoms and do not appreciate the importance of protecting themselves from the risks of HIV infection. Their frequent mobility also poses a problem as it makes it difficult for them to benefit from health education campaigns. The prevalence of HIV-1 infection among female prostitutes in Borno State (as indeed in other States in Nigeria) is likely to rise sharply in the next few years unless serious efforts are made to intensify health education campaigns targeted at the high risk groups.
