    Abstract Continuous improvement has led to a very high degree of microbial safety of transfusion. Four issues are likely to impact the future of this safety. There will be further advances in the efficacy and efficiency of donation testing and pathogen reduction, increasing safety and hopefully eliminating unnecessary procedures. While system failures have been essentially eliminated, there will be ongoing, unpredictable issues that are inevitable. Emerging infections are likely the greatest concern and will continue, although advances in science and technology will permit increasingly rapid responses to outbreaks. Finally, the practice of transfusion may eventually impact safety as usage of blood is reduced and perhaps as alternatives to conventional blood components are developed.

    Abstract Background: Anaplasma phagocytophilum is a tick-borne bacterium and the cause of human granulocytic anaplasmosis (HGA). Here, we report a case of transfusion-transmitted (TT)-HGA involving a leukoreduced (LR) red blood cell (RBC) unit.
    Case report: A 64-year-old woman with gastric adenocarcinoma and multiple myeloma who received weekly blood transfusions developed persistent fevers, hypotension, and shortness of breath 1 week after receiving an RBC transfusion. Persistent fevers, new thrombocytopenia, and transaminitis suggested a tick-borne infection.
    Results: The absence of blood parasites on thick and thin blood smears suggested that malaria and Babesia infection were not present, and the recipient tested negative for antibodies to Borrelia burgdorferi. Blood testing by polymerase chain reaction (PCR) for Ehrlichia and Anaplasma species identified A. phagocytophilum. Treatment with doxycycline resolved the infection; however, the recipient expired due to complications of her known malignancies. The recipient lived in a nursing home and did not have pets or spend time outdoors. The donor was a female in her 70s from Maine who was diagnosed with HGA 3 weeks after donating blood and whose LR-RBCs from the donation were transfused to the recipient 9 days following collection.
    Conclusion: This is a confirmed case of TT-HGA. Although rare, TT-HGA has been reported with LR-RBCs and platelets. In endemic areas, testing for tick-borne associated infections should be considered when investigating post-transfusion complications.

    Abstract We evaluated antibodies to the nucleocapsid protein of SARS-CoV-2 in a large cohort of blood donors in the United States who were recently infected with the virus. Antibodies to the nucleocapsid protein of SARS-CoV-2 indicate previous infection but are subject to waning, potentially affecting epidemiologic studies. We longitudinally evaluated a cohort of 19,323 blood donors who had evidence of recent infection by using a widely available serologic test to determine the dynamics of such waning. We analyzed overall signal-to-cutoff values for 48,330 donations (average 2.5 donations/person) that had an average observation period of 102 days. The observed peak signal-to-cutoff value varied widely, but the waning rate was consistent across the range, with a half-life of 122 days. Within the cohort, only 0.75% of persons became seronegative. Factors predictive of higher peak values and longer time to seroreversion included increasing age, male sex, higher body mass index, and non-Caucasian race.

    Abstract Background: U.S. blood donors are tested at each donation for human T-lymphotropic virus (HTLV) antibodies. Depending on donor incidence and other mitigation/removal technologies, a strategy of one-time selective donor testing should be considered.
    Methods: Antibody seroprevalence was calculated for HTLV-confirmed-positive American Red Cross allogeneic blood donors from 2008 to 2021. Incidence was estimated for seven 2-year time periods using confirmed-positive repeat donors having seroconverted in 730 days. Leukoreduction failure rates were obtained from internal data from July 1, 2008-June 30, 2021. Residual risks were calculated using a 51-day window period.
    Results: Between 2008 and 2021, >75 million donations (>18 million donors) yielded 1550 HTLV seropositives. HTLV seroprevalence was 2.05 antibody-positives per 100,000 donations (0.77 HTLV-1, 1.03 HTLV-2, 0.24 HTLV-1/2), and 10.32 per 100,000 among >13.9 million first-time donors. Seroprevalence differed significantly by virus type, sex, age, race/ethnicity, donor status, and U.S. census region. Over 14 years and 24.8 million person-years of observation, 57 incident donors were identified (25 HTLV-1, 23 HTLV-2, and 9 HTLV-1/2). Incidence decreased from 0.30 (13 cases) in 2008-2009 to 0.25 (7 cases) in 2020-2021. Female donors accounted for most incident cases (47 vs. 10 males). In the last 2-year reporting period, the residual risk was 1 per 2.8 million donations and 1 per 3.3 billion donations when coupled with successful leukoreduction (0.085% failure rate).
    Conclusions: HTLV donation seroprevalence for the years 2008-2021 varied by virus type and donor characteristics. Low HTLV residual risk and use of leukoreduction processes support the conclusion that a selective one-time donor testing strategy should be considered.

    Abstract Background: Hepatitis C virus (HCV) infection rates among US blood donors have been well characterized; however, few studies evaluated HCV genotypes among blood donors. Monitoring trends in disease and demographic patterns contributes to understanding the safety of the blood supply. We examined the demographic characteristics and distribution of HCV genotypes/subgenotypes for nearly a 16-year period among blood donors confirmed positive for HCV RNA but antibody negative (defined as nucleic acid testing [NAT] yield).
    Methods: A retrospective assessment of demographic characteristics and testing data was used to determine temporal trends and geographical distribution of HCV genotypes/subgenotypes among American Red Cross blood donors confirmed positive as HCV-NAT yield.
    Results: From 2003-2018, 343 donors (0.38/100 000 donations; 95% CI, .35-.43) were confirmed positive as HCV-NAT-yield cases. Temporal analysis revealed a significant increase in HCV-NAT-yield cases of 54.1% between 2009 and 2014 (P = .014), followed by a significant decline of 31.4% between 2015 and 2018 (P = .002). Significantly more HCV-NAT-yield cases were detected among first-time donors, non-Hispanic Whites, donors aged 20-29 years, equally likely to be males as females, with the highest frequency in the South (0.52/100 000 donations). Subgenotype 1a (49.6%) was most frequent, followed by 3a (18.7%), 2b (12.5%), 1b (8.5%), and 2a (1.7%).
    Conclusions: Voluntary nonremunerated blood donors are at low risk for HCV infection. Since 2015, the frequency of HCV-NAT-yield cases decreased despite an increase in acute HCV infection in the general population. HCV subgenotypes 1a and 3a continue to remain predominant among US blood donors with recent HCV infection.
