Wow. I'm so happy this turned out well for you.
My wife is just coming out of a 2 week fight with the flu. This year's batch is wrecking shop.
Dad of a kid on my oldest's basketball team couldn't get his fever under 103 for 5 days. His kid is probably the 2nd or 3rd best player on the team. We had a game on Saturday, and the first three times he touched the ball, he turned it over. I said, uh oh, sure enough, he's been out all week.
I think what we've seen here is how long its lingering. usually its like 48 hours, sweat it out, puke it out, and you're back. I've seen people who are a week plus and can't shake the fever.
One of the better post-COVID developments is acceptance of work from home. We used to have to shove our kids out the door sick, if they didn't have a fever, because neither one of us could take another day. You'd have people hacking up their strep throat all over everyone at the office. Now that I have a full home office, as does our whole office, I've noticed a HUGE difference in how often people are sick, simply because they don't have to force themselves in sick because they can't take a day, and working from home is inefficient. Hell, during the school year, when kids are gone I'm far MORE productive from home, simply because the people who report to me, think twice before a phone call question, that they already know the answer to, and I don't get caught in a 20 minute small talk trap with someone from HR at the copier
