Prevalence data from the first four years of the Transfusion-Transmissible Infections Monitoring System (TTIMS) provided below shows HIV, HBV and HCV prevalence per 100,000 donations at 6-month intervals from October 1, 2015 – September 30, 2019. TTIMS combines data from four US blood collection organizations (the American Red Cross, New York Blood Center, OneBlood and Vitalant) to represent ~60% of all U.S. donations. The figure from a recent publication in Transfusion (https://doi.org/10.1111/trf.16005) shows no significant change over time for HIV, HBV or HCV rates after the implementation of the 12-month MSM deferral (from indefinite). The yellow band indicates 12-month MSM implementation period at the four TTIMS centers. Implementation of the reduced MSM deferral occurred from August to December 2016. Six-month intervals are notated on the x-axis by combined quarters. For example, 15Q4_16Q1 is 2015 Quarter 4 and 2016 Quarter 1 combined. Linear regression used to test for trend: HIV (R2 =0.063, p=NS), HBV (R2 =0.045, p=NS), HCV (R2 =0.061, p=NS).
