i feel like this is just explained by sick days, flu season was crazy this year

post-covid people are more hesitant to send their kids to school slightly sick or when there are sick siblings / parents in the household.

This!

We don't send our kid to school with fever. Sending your kid to school with a low fever used to be very normal. But post-COVID we are more tempted to check the temperature when the head feels warm. But actually the better way to 'measure' a fever is how much a child is playing and energetic.
