And in a similar vein, I read somewhere (now can’t recall where) about some viral illness (can’t recall which one) that was rampant in kids in Vic over summer for the same reasons. As my kids would say, good story mum
The point was that the Vic kids didn’t get whatever it was whilst they were locked down, but it was still endemic in the community, and as soon as they came out, they all got it in a big rush. There was also some commentary about the kids having reduced immunity because of lack of exposure. I’ll search to see if I can find the original news item.
