Appendix 1—figure 20. Seroprevalence in December 2020 disaggregated by race and education level.
The seroprevalence was estimated using a threshold of 0.1 signal to cutoff and correcting for sensitivity and specificity, without any explicit correction for seroreversion. To aid visualization, we merged the White and East Asian races and discarded Indigeneous individuals. Information on education level is available for very few donors in Manaus, hence, the large confidence intervals.
