you do realize that fauci and cdc were were pleading for more protective N95 masks for healthcare workers at the same time they were telling the general public that masks were unnecessary and might even be harmful? damn, how soon they forget-eh?Do you think all viruses spread through the air? Human immunodeficiency VIRUS is not spread through airborne droplets. The word virus doesn't automatically mean you need to wear a mask to control the spread.
The Middle Eastern Respiratory Sydrome (MERs-CoV) is also a coronavirus, but human to human transmission has only been determined where prolonged, close exposure to an infected person has occurred. Because it doesn't spread as freely, widespread mask use was not required.
At the time the CDC made the statement, the evidence was not there to support wearing masks because most of the novel coronavirus cases that have spread to humans have had limited success with person to person infectivity.
Hindsight shows they were wrong, but they corrected themselves once the evidence came out. Again, its not about never being wrong, its about forming an opinion based on credible evidence and changing that opinion when the evidence changes. I have no idea why they recommend wearing 2 masks or whether that is based on anything, and if its not i would question that 100%.
it had nothing to do with hindsight, they outright lied!!! fauci and cdc has blood on their hands, imagine how many lives could have been saved if they had come out in march 2020 and told the general public to wear masks!!!
