HIV-Sero-prevalence trend among blood donors in North East Ethiopia

BACKGROUND Although blood transfusion is one of the known therapeutic interventions that cuts across a number of clinical disciplines. It is necessary to test all intending blood donors for HIV infection before donation. The aim of this study was to determine the prevalence of HIV among blood donors at Dessie Blood Bank, Northeast Ethiopia. METHODS A retrospective study was conducted in Dessie Blood Bank through the year 2008-2012. Sera from blood donors were tested for the detection of Anti HIV by using 4th generation ELISA. Data were abstracted from records and analyzed using Microsoft Excel sheet. RESULTS From the total of 9384 screened blood samples collected, the prevalence of HIV in blood donors in the blood bank was 5.1% in the five consecutive years but the trend of HIV infection has decreased from 2008(5.2%) to 2012 (2.3%). The age groups 15-24 and 35-44 were the highest prevalence and the age group 45-54 was the lowest prevalence of HIV infection. The prevalence of HIV among female (7.9%) was higher than in male donors (4.4%). The trend of HIV infection was decreasing for both male and female blood donors. CONCLUSION The prevalence of HIV infections among blood donors is still high in this study setting, and needs constant monitoring to evaluate prevention and control strategies to reduce the burden of transfusion-transmissible HIV infections.
