This study was realised in collaboration with Walter Reed Army Institute of Research. Three different kinds of cohort recruiting were compared. Over a four year period, HIV incidence and prevalence rates were determined, basal data for viral load, cd4 and cd8 kinetics, risk behaviour and follow-up rates was generated.
Through an information campaign, knowledge about vaccine studies, and willingness to participate in such studies has been improved. In September 2005, the 3,000 participants have been observed for three years. HIV prevalence was determined to be 18,4% in urban and 12,2% in rural population, incidence of new infection was 1,6%, and interestingly was higher in rural than in urban areas. Follow-up rate after three years was 85%.
