I think that concern is just a guess that with mutation of the virus, there might become stronger strains which may impact people that already contracted the virus. There were studies that the mutating is actually weakening the virus, but only time will tell what a 2nd wave will look like. I think a 2nd wave is inevitable, but it might not be as bad as what we’ve already seen. Typically flu season (I’m not comparing the two other than the time frame) is from the middle of November to the end of March. That’s not set in stone, you can catch the flu in October, and May, but that timeframe is typically when it’s more widespread. We haven’t seen what will become of the virus when heat is consistently high and humidity is up, but some states won’t reach consistent 90-100 degree temps AND 80-100% humidity, so while it could stay dormant in some states, other states might have the problem where it may stay around and get back to being widespread in November/December. Only time will tell
