Right now in America there are literally thousands of people walking around with covid-19 and they don't even know it
Wearing a mask drastically reduces the chance of transmitting the virus by those that have it
Healthy people in addition wearing a mask drastically reduces the chance of inhaling it.
Combined, the viruses chances of spreading are knee capped
The WHO in the beginning sucked in their knowledge and were too slow to act. Their advice used to assume the virus was not all that airborne and not transmitted by asymptomatic people. And would not carry through the air in aerosols but large droplets. We know that's all BS now. Hence, mask is important. No you don't need a surgical P95 mask all hours but a cloth one while not perfect, if worn by everyone would go a long way while being comfortable
If repugnicans really wanted to assure Trumps presidential election victory, they would get behind this. Why? Because in 6 weeks, the number of community transmissions would be negligible. By the time of the election, Trump could boast behind defeating the virus
Keep on track and the greatest number of casualties will be dumbarse repugnicans who would otherwise have given Trump their vote.
Seriously not hard stuff.
