Figure 3: Viral loads over time in children from A) 0-9 and B) 0-19 year olds.
Orange data points indicate tests done on LC480 machines, black on cobas. Community/cluster testing includes children tested at walk-in clinics, as well as those tested due to having contact with a SARS-CoV-2 positive individual, asymptomatic cases, and family clusters. ‘Other clinical centres’ includes children tested in hospitals. The dotted line denotes a log10 viral load of 5.4, corresponding to 250,000 viral copies.
