“…Seroprevalence estimates have varied widely, however, due to differences in sampling approaches, the target population, and the dates during which surveys were implemented [ 18 , 24 ]. In addition, general population estimates may not take into account the higher rates of infection among subgroups; for example, several studies have demonstrated that Latinx communities in the U.S. are more highly affected by the pandemic, likely due to occupational hazard, higher housing density and other factors [25] , [26] , [27] , [28] , [29] , [30] . Errors in prevalence estimates can also occur because of imperfect antibody test performance, which can under- or overestimate actual infections [ 24 , 31 , 32 ].…”
