Fig 5
Conceptual figure on how a discrepancy between the test validation and serosurvey data can be detected.
(A) Histograms of simulated validation data from controls and severe cases. (B) Histograms of simulated validation data from controls and severe and asymptomatic cases. (C) Histogram of simulated serosurvey data when all infections in a population are severe. (D) Histogram of simulated serosurvey data when one third of all cases is asymptomatic and two thirds severe.
