From common sense. If every single person in America were all tested for covid right this second. What percentage would we guess has an active covid infection and is contagious?TraditionKU wrote: ↑Thu Oct 07, 2021 12:28 pmwhere did the bolded info come from?randylahey wrote: ↑Thu Oct 07, 2021 12:11 pm Science goes both ways tho. Only a small percentage of people have covid at any given time. Take that small percent multiply it by the likelihood of them transmitting it to someone else. Take that small percent multiple it by the odds that person is vulnerable to covid. Then add a mask to the equation and take that percent and multiply it by the odds of the mask preventing the spread
When you start looking at all the variables, you realize that the odds are so so so ridiculously low
You can't spread covid if you don't have it
