Figure.. Frequency of Reactivity in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Antibody Testing by Week, June 15 to August 23, 2020, in the 4 US Census Regions
Each region is represented by a different line; the dashed line represents the total percentage seroreactivity. Each point is the mean of the overall data for that week (for each of the 10 weeks), with error bars representing the associated 95% CIs. The text provides the total number of anti–SARS-CoV-2 reactives and the key also provides the total number reactive/total number of donations by US Census region, including the number of donations tested.
