This is not simply a new strain of flu, around 50,000 people in US die of flu a year with no lockdowns over a year. This virus has killed over 115,000 in 12 weeks even with all the precautions and the states that thought it was fine to open up are now have huge increases and trying to figure out ways to back up on their opening up so soon. Arizona is one state where there emergency rooms are full so if you have a heart attack or car accident good luck finding a place to take you. They opened about 3 weeks ago.
The 2nd wave of the 1918 pandemic killed more people than the first because they didn't want to take precautions anymore and went back to living as if nothing was happening.
