For about 3 months anyway.At least you've got a natural immunity to it now. But it doesn't help that this is the normal time people get a cold or the flu.
The schools around here will send anyone home who has a cough, even if it's not COVID. I kept my youngest home today just to see how his cough was and he seems fine to go back tomorrow...thankfully! I don't want him getting behind because they're no more prepared for kids being out than they were when virtual learning started.
