The number of cases in recent weeks has skyrocketed while the death trend continues to go down. Granted there is a lag between a positive test and a death for a particular individual, but I think we would start seeing the daily death toll increase by now. I think either the virus mutated into a weaker form or it has been a lot more widespread than the experts thought and more testing is just confirming that. Treatment of the seriously sick may also better as better protocols and drugs are available. I think the bottom line is it will be around for a long time to come and humanity will work through like thousands of other bugs throughout the eons.
