If someone caught HIV few days before blood donation, would the person receiving blood also get HIV since even blood testing at this stage would not reveal any signs of the virus.
The risk of transmission is at its height after the eclipse phase(early stage), at this stage the infection is extremely localized to the exposure site, hence there is no "true" viremia, and the patient cannot transmit the infection. The eclipse phase takes approximately 7-12 days. Following this virus replication occurs, proviruses are produced and with the help of viral protease the virus buds extracellularly and disseminaties to lymphoid tissues and hence causes a viremia. It is at this stage that patients easily transmit the infection, this would be Fiebeg stages 1 and 2, typically after 12 days of the primary infection, it is when the most viral RNA can be detected in the circulation.
All blood donors are prescreened for HIV risk factors.
Blood donations are required to be tested both for presence of antibodies to HIV and for HIV ribonucleic acid (RNA). RNA testing detects HIV at an earlier stage than HIV antibody testing.
Blood and blood products that test positive for HIV are safely discarded and are not used for transfusions. Donors whose blood tests positive for HIV are notified by the collecting agency and are deferred from further donations.
You should not donate blood to find out if you are HIV-positive,because the HIV tests used to screen donor blood are highly accurate but an althoughrarely ssomecases may bemissed . If you have been infected with HIV recently, even the most sensitive test may not show it, and you can infect others if your blood is transfused to them.
If you have engaged in high-risk sexual or drug taking behaviors, you should not donate blood. It is important, though, to learn your HIV status.
