From: Age-specific rate of severe and critical SARS-CoV-2 infections estimated with multi-country seroprevalence studies

Fig. 1

Rates of severe and critical SARS-Cov-2 outcomes (ISR and ICR, respectively) and death rates (IFR) estimated with seroprevalence data from 2020. The colored points show the proportion of individuals infected with SARS-CoV-2 that develop severe disease (left), critical disease (center), or fatal disease (right) (in logarithmic scale) for each location and age-stratum used in our analysis. Color indicates whether the number of infections were obtained from a representative serosurvey, a convenience serosurvey, or from comprehensive testing corrected for under-ascertainment. Data points coming from a given location are joined by colored lines. The black line shows the outcome rate estimated using a hierarchical Bayesian logistic regression model, and the shaded regions show the 95% credibility intervals. We used 105 data points from 16 locations for the estimation of ISR, 78 data points from 11 locations for ICR, and 119 data points from 17 locations for IFR
