Another anecdote:
Wife's parents came from out of state to stay with us for a week in early Janurary for a late Christmas.
-FIL, who is in his early 60s but very very healthy, shows up with an awful hacking dry cough. Says hes had it for almost a week and has mild fever a few days prior. Cough last for the duration of their stay with us.
-Towards the end of the week, MIL starts developing same cough and mild fever. One night after supper she starts experiencing acute shortness of breath and severe coughing fits, she is obviously shaken. It lasts most of the night, my RN wife is about to take her to local ER when she finally starts breathing well enough to get some rest. They leave a couple of days later but not 100% fully recovered.
-A day or two after inlaws leave both my kids (2 and 4 yo) develop mild cough and fever. This lasts approx. 3 days each. My kids are pretty resilient but my son is hit hard and can barely get off the couch during the day.
-My wife in her early 30s gets the same thing on the tail end of my kids illness. Headache, fatigue, cough and mild fever. This lasts about 4-5 days and shes back to 100%.
-I have managed to avoid any illness, despite having my kids constantly trying to drink after me and coughing into my face but it finally catches me. I use three sick days for work during the worst of it. It lasts about 5-6 days at the peak. I was the only one who went to see a doc, negative for both flu and strep. Says its probably viral, and gives me z-pack (ok?)
-During this same time the public school in our town shuts down for almost a week, due to almost half the students being home sick with flu like illness.
Cant draw any solid conclusion from these early to mid January events but it sure does seem odd to me given the appearance of the first documented covid case shortly after.
