I agree. Just got back from a trip to Columbus, OH. Flew Southwest. Plenty of people in Atlanta airport coughing. Plenty on the plane coughing.
I found myself holding my breath as oriental folks walked by. Not that it would do much good.
Side note. I do not feel well now, hopefully just a cold. Headache, sinus drainage and inklings of chest congestion. This was a quick trip and I am on day 4 from when I took off. Plenty of sick people flying and even with that it’s more likely the same cold my daughter has been fighting for a while now. Went to the doctor for her, turned out to be an ear infection initially. Antibiotics and drops for ear but I think her immune system was weakened and she picked up a nasty bug. Now it appears I have that same bug.
Just say no to the Wu Han Flu.
If there were multiple people coughing on your plane then you probably caught whatever they had. I once rode a greyhound and there was one guy with a flu talking in his phone loudly for 15 minutes. Got it 4 days later. Nasty one too.
