The relative scarcity of children recorded with confirmed cases of #COVID19 has been remarked on repeatedly. However, I actually hadn’t noticed until today that SARS in Hong Kong in 2003 also showed a scarcity (from @gmleunghku et al https://www.acpjournals.org/doi/10.7326/0003-4819-141-9-200411020-00006). 1/2

Generally, I haven’t seen persuasive evidence for why children aren’t getting as sick. Though note that from seroprevalence studies children do get infected (from @hendrikstreeck et al https://www.medrxiv.org/content/10.1101/2020.05.04.20090076v2). 2/2
