I'll put myself as a strong maybe. Covid first documented cases in US were end of January. I was traveling out west during that time, Phoenix area to be specific. On January 29 I flew back to Chicago. Two days later I very suddenly became very ill with fever, sore throat, mild but persistent cough and some serious body aches. This lasted about 5 days, with days 1 thru 3 being the worst. Symptoms left but fatigue and overall loss of strength stayed a good 3 to 4 weeks. That was the one thing I had never experienced before, the lingering weakness which is supposed to be common among people who have had Covid.
