SARS-CoV-2 case surveillance in the United States did not distinguish first infections from reinfections. In a large blood donor cohort, self-reported first infections and reinfections during 2020-2022 mirrored public health case count surveillance, and reinfection incidence peaked in 2022. Blood donor data could aid in SARS-CoV-2 and emerging infectious disease surveillance.
美国对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的病例监测并未区分首次感染和再次感染。在一个大型献血者队列中,2020年至2022年期间自我报告的首次感染和再次感染情况反映了公共卫生病例计数监测情况,且再次感染发病率在2022年达到峰值。献血者数据有助于SARS-CoV-2及新发传染病的监测。
