Prevalence of human T-lymphotropic retroviruses type III (HIV) and type IV in Ivory Coast

Abstract

Serological investigations in the Ivory Coast indicate that, despite the rarity of overt acquired immunodeficiency syndrome (AIDS), human immunodeficiency virus (HIV) is widely prevalent. So also is human T-lymphotropic virus type IV (HTLV-IV). The highest rates of HIV and HTLV-IV seropositivity were observed in female prostitutes. These findings suggest that, like HIV, HTLV-IV can be transmitted by heterosexual contact, and that the mobility of prostitutes may be an important factor in spread of the retroviruses in Africa. The incidence of HIV-associated AIDS in the Ivory Coast is likely to rise sharply in the next few years.
