High levels of HIV prevalence and incidence have been recorded in Zimbabwe since sentinel surveillance was introduced in 1990. Prevalence levels in excess of 40% have been recorded among women attending antenatal clinics in a number of urban centres [1,2]. In a cohort study of male factory workers conducted in Harare between 1993 and 1995, 19% of participants were found to have the infection at enrolment and an incidence rate of 2.93% per annum was recorded [3]. However, rural areas - where 70% of the country's population are based - are experiencing some of the highest rates of incidence at the current time. In Mberengwa, Midland Province, HIV prevalence among pregnant women increased from under 8% in 1992 to 25% in 1994 [4].
