Interesting preliminary COVID data from Australia. Small numbers, but potentially suggestive of limited transmission to and from children... http://www.ncirs.org.au/covid-19-in-schools

One notable caveat is it looks like the primary cases were identified based on symptoms, so if there were chains of asymptomatic transmission happening, they may not have been picked up.

And some additional important caveats noted here: https://twitter.com/DrZoeHyde/status/1254287354832941058?s=20
