 AB    OBJECTIVE: To monitor the effectiveness of blood donor screening
       procedures and HIV testing in the National Blood Transfusion Service of
       Zimbabwe. (NBTS) METHODS: New procedures for blood donor screening were
       implemented and HIV figures were monitored from all the 5 NBTS centres.
       Different categories of blood donor populations were analysed. Western
       blots were done on all indeterminate ELISA results on repeat donations.
       RESULTS: Presently, the all inclusive HIV percentage in total blood
       donations is less than 2% from an upward trend which was exceeding 5% by
       1989. Adults had higher prevalence figures than Secondary school boys
       and girls, and girls had higher figures than boys at Secondary schools.
       Some regular donors are sero converting. Western blot results have
       cleared many donors. DISCUSSION AND CONCLUSIONS: The current 2% may look
       like an achievement compared to the estimated seroprevalence in the
       general population but there is need to improve on this yet still obtain
       sufficient blood to satisfy the demand. The Secondary school donors
       contribute more than 60% of the total blood collected but the risk of
       HIV infection increases as they become sexually active.
