While the rate of infections has increased exponentially ,the deaths per day have fallen off from over 2000 a day in mid April to less than 500 per day now. Being objective about it the only logical conclusion is it has mutated and is no longer nearly as deadly as it was in April, and it is now widespread throughout the entire population. Once it is endemic trying to stop it is pointless really, like trying to empty the ocean with a table spoon.
