“…A number of studies reporting anti-SARS-CoV-2 seroprevalence data have been published (Barzin et al, 2020;Biggs et al, 2020;Chen et al, 2020;Hallowell et al, 2020;Kshatri et al, 2020;Lai et al, 2020;Majdoubi et al, 2020;Makaronidis et al, 2020;Murhekar et al, 2020;Picon et al, 2020;Rudberg et al, 2020;Song et al, 2020;Squeri et al, 2020;Stadlbauer et al, 2020;Takita et al, 2020;Wells et al, 2020), including a few with respect to blood donors (Amorim Filho et al, 2020;Erikstrup et al, 2020;Fiore et al, 2020;Fischer et al, 2020;Gallian et al, 2020;Ng et al, 2020;Percivalle et al, 2020;Younas et al, 2020). Our results are consistent with these reports in that seroprevalence estimates are generally low, albeit often several-fold higher than cumulative COVID-19 incidence rates.…”
