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.
