( A) Distribution of observed first-positive viral loads for 25,381 subjects according to clinical status (6110 PAMS, 9519 Hospitalised, 9752 Other) and age group. ( B) Age-viral load association with observed viral loads and confidence intervals as circles (with size indicating subject count) with vertical lines, and model-predicted viral loads and credible intervals as a black roughly-horizontal line with grey shading. ( C) Overlapping age histograms according to subject clinical status. Because inclusion in the study required a positive RT-PCR test result, and testing is in many cases symptom-dependent, the study may have a proportion of PAMS cases that differs from the proportion in the general population.
