RETROSPECTIVE STUDY OF PREVALENCE OF HIV IN BLOOD DONORS AT A.D.GORWALA BLOOD BANK

Abstract

Background: India has the second highest HIV population in the world with about 2.5-3.0 million cases. Blood transfusion saves millions of lives worldwide each year but Blood transfusion is an important mode of transmission of infections to recipients and at the same time it is also associated with large number of complications including transfusion-transmissible infections (TTIs). Aims & objective: to study the prevalence of HIVin blood donors of A.D.Gorwala Blood bank From January 2005 To December 2010. Methods: A retrospective study was conducted among blood donors through the years 2005-2010. Sera from blood donors were tested for the detection of Anti HIV by using third generation ELISA tests, strictly following the instruction of manufacturers. The donor information was collected through the donor registers from A.D. Gorwala Blood Bank. Result: From the total of 28,371 screened blood samples collected, the prevalence of HIV in blood donors in the blood bank was 0.23% in the ve consecutive years but the trend of HIV infection has decreased from 2005(0.31%) to 2010 (0.04%). The age groups18-30 has the highest prevalence and the age group 51-60 was the lowest prevalence of HIV infection. The Prevalence of HIV among male (0.18%) was higher than in female donors (0.05%). The trend of HIVinfection was decreasing for both male and female blood donors. Conclusion: The analysis of HIV seroprevalence among blood donors through the year 2005- 2010 showed a signicantly decreasing trend, probably due to the cumulative effect of increasing awareness of HIVand improved screening system for safe blood donation.
