      OK I'm busy trying to catch up with what I've missed on #COVID19 in children, which looks like a lot! People seem to be making a big deal out of some new papers, but frankly there's not a huge amount of new information here - quick run down 1/13

      Over such a brief period of time, likely kids didn't actually have time to transmit to each other. Mainly got infected by staff Good break down here by @DiseaseEcology (although I disagree with the take on household transmission studies!) 3/13https://twitter.com/DiseaseEcology/status/1289298074804711425?s=20 …

      Rampant #COVID spread in a kids camp: a preview of school re-opening? New paper with unsettling details that unfortunately challenges claims that transmission in young children will be lower than adults. More useful info on %asymptomatic too!

      We've known for some time children can get infected in mass spreading events, albeit has mostly been demonstrated in older children (see study from France) Attack rate is pretty high though! 4/13https://www.medrxiv.org/content/10.1101/2020.04.18.20071134v1 …

      Next an outbreak in a high school in Israel We cannot tell direction of transmission, but to me this looks like too many cases too fast to all be spread between children; I imagine multiple sources of entry Secondary schools do seem higher risk 5/13 https://www.eurosurveillance.org/content/10.2807/1560-7917.ES.2020.25.29.2001352 …

      Many do not mention this important detail in this outbreak report: “The rate of cases reporting symptoms, upon meticulous questioning, was 43% (66/153) among students and 76% (19/25) among staff.” I feel that self isolation with symptoms is still not appreciated..

      Dr Cevik, do you mean that those with symptoms did not self-isolate here & and thus much could have been gained if they had?

      Yes. They attended classes while symptomatic.

      That is very different from Sweden, where symptomatic children stayed home and sent home if at school. May have contributed to the zero death count and very low hospitalization among the 1.8 million children attending school during the height of the pandemic.
