Again you are the one playing ifs. You throw out all the ifs that lighten the outcome when you do a worst case scenario.. hence the name worst case
Worst Case scenarios assume every possibility you can think of is bad.. hence the name. And if you worst case this disease with 20 million infected in a brief time you get 2-3 million deaths.
Well them we will just watch and pray, and see how this all turns out. I agree that a lot of fear and misinformation being repeated and spread has been the case.
