My 39 year old son has COVID. He returned to the Midwest after visiting his brother on the West Coast. Three days later he wasn't feeling well, and took a home test, then went to be seen by his doctor. My wife and I had picked him up at the airport and driven him home, a 35 minute trip. He has 2 more days to quarantine, so we won't see him this weekend, a rare occurrence. So far, my wife and I, as well as his brother's family (2 kids) have not gotten sick. None of us have ever tested positive until now. Thankfully, COVID is now usually mild for fully vaccinated individuals like our son. He is already feeling better.
Bottom line: stay vigilant, it's not over! Well, it's endemic now, whether that's been declared officially or not. I'll be asking my doctor if I should get the new Omicron vaccine. I've had 2 booster shots already.
