Incidence and window period residual risk of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in United States blood donations, 2017 to 2023: The transfusion‐transmissible infections monitoring system

Despite reducing donor deferral periods for many infectious risk behaviors, HIV, HBV, and HCV overall incidence declined from the 12M to 3M periods. WPRR also declined from 12M to 3M, remaining under 1 per 2,000,000 donations in the 3M period. Thus, changes in policy did not adversely impact the safety of the blood supply with respect to the major infectious disease agents.
