From: High seroprevalence of anti-SARS-CoV-2 antibodies among Ethiopian healthcare workers
A map of Ethiopia showing the location of the study hospitals with corresponding SARS-CoV-2 seroprevalence. a Shows the location of five hospitals from which a total of 1997 healthcare workers enrolled between December 2020 and February 2021. b Shows the corresponding seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The y-axis of Fig. 2b represents the study hospitals. The x-axis of Fig. 2b shows crude seroprevalence rates (%) with 95% confidence intervals estimated by dividing the number of participants tested seropositive for immunoglobin G (IgG) antibodies elicited against the receptor binding domain (RBD) of the spike protein of SARS-CoV-2 to the total number of participants who provided sera and were tested
