Too many unknowns about this. There are people left with long term health issues, some I know of personally. People with very mild cases that went away in a few days have been left with heart, lung, and circulatory damage they didn't have previously. Not everyone, but some. My daughter was pretty sick for 7-10 days, but fully recovered. Another friend was an extreme athlete who ran marathons had a mild case in April. She still can't run more than 2 miles from lung damage that hasn't healed yet. There have been several college age athletes who tested positive, but were asymptomatic. They now have heart damage.
