I can. Flu, RSV, croup, and common cold infection rates went down so much during the pandemic that it is creating a problem for 3-4 year olds. The pediatrician just told me that masking up stopped the transmission of so many respiratory viruses. So much so that little immune systems that would have grown up with an infection/exposure to some new nasty bug. On a weekly/monthly basis. Weren’t exposed to much at all. Now they are catching everything all at once. It is no fun for them. Turns out getting sick is how your immune system develops in a normal and healthy way. Who knew masking up was so safe it is dangerous. Now us parents that have little ones are spending 6 months cycling through everything they can catch.
