1. Transmission of infected blood carries a 100% chance of transmission . However, worldwide ( as also in the armed force) HIV infection due to transfusion of infected blood accounts for only 5% to 10% of all HIV infection. Testing of all donated blood for HIV is the effective method of preventing such eventuality though the possibility of missing out a donor (false negative result) during window period remains a remote possibility .
2. Whole blood, fresh frozen platelets, packed cells and clotting factors have been demonstrated to carry HIV. On the other hand, albumin, Immuno-globulin (including RH-anti D immunoglobulin) and Hepatitis B vaccines derived from human or recombinant sources have not been found to transmit HIV because of the purification processes which inactivate the virus .Allograft and organ transplants do carry definite risk ; kidney transplants have been shown to carry maximum risk . Donor semen has also been shown to carry risk.
