... Fact: 70% of those infected wore masks AND followed CDC guidelines.
The reason why to wear masks was from the beginning to protect others not to be infected. The main problem: Some people are infected and don't have big problems while they infect others. After some time we found out that masks help also not to infect the own person. But this effect is secondary. Both effects slow down the speed of the infection (=the number of the people who are infected at the same time) and give more people the possibility not to have to die alone in the gutter but to get a chance to be healed in a hospital.
First of all you had to know who infected this 70% - if your data are not pure fantasy, what's also possible. I fear when Corona wil be over then you will still deny that you will have lost more than the 418,000 people which you lost during world war 2 - within a much shorter time. THIS DAMNED VIRUS HAS NO FEET! So in case of everyone, who died, someone else carried the virus to this people. AND NOW TAKE CARE NOT TO KILL YOUR PARENTS OR GRANDPARENTS AT CHRISTMAS!
Why for heavens sake is it so difficult for US-Americans to fight consequently against a deadly virus? Is it your own wrong pride and vanity which kills you in masses? What for heavens sake are your real problems, which help this virus to kill you?
