Even the tests to screen donated blood can fail if the infection has been contracted three months before donations. But still, hospitals seek replacement donors because there is a scarcity of voluntary donors and hospitals have to maintain their stocks. In a study, published in Indian Journal of Hematology and Blood Transfusion, to find prevalence of Transfusion Transmitted Infections (TTIs) in voluntary and replacement donors found that out of 9,599 blood donors, 58 (0.6%) were tested reactive for blood transmitted infection and out of these, 38 (65%) were replacement donors. The prevalence of HIV was 0.06% in total donors; 4 in replacement and 2 in voluntary. The prevalence of Hepatitis B in total donors was 0.34% (33 cases)...
