My niece’s husband got it in March of last year. He was too sick to go to work for nearly 3 weeks and it took several more months until he felt he was completely recovered. FWIW he’s in his early 40’s, very physically fit, doesn’t drink, doesn’t smoke and has no co-morbidities.
I have heard a number of similar stories. The scariest was the friend of one of my employees—29 year old healthy female (half-marathoner!) who contracted COVID-19 and “recovered.” Six months after her “recovery,” she still couldn’t climb stairs without using an inhaler prescribed by the doctor. Her lungs were basically destroyed by the virus.
I had it last June, drink like a fish, eat red meat and I lost my taste and smell for a month and that was it. Was a joke. I’ll take Covid over the flu any-day.
And my 60 year old brother who is obese, diabetic, alcoholic, kidney problems, and Parkinson's got it and sailed through it with NO problems at all.
Likewise for someone I know who is a transplant patient with no immune system to speak of.
