What is 1.8%. The effectiveness of a mask? I saw the new CDC numbers that put it at 1.32%. Meaning that if there is a 1/200 chance I have corona. There is maximally a 0.5% chance I could give it to you by talking to you. It can't be higher than the chance that I myself have corona but is probably less. By wearing a mask you now have a 0.4934% chance of getting it instead o 0.5%. So we reduced your odds by a total of 0.0066%, of getting a disease with a 99.7% survival rating for your age group, for which 90% of deaths can be attributed to insufficient vitamin D, so you could just take some vitamin D and Zinc (while we are at it) and up your odds to 99.97% survival rate. So by wearing a mask I reduced your odds of dying as a result of our interaction fell by 0.00000198% if you have brains enough to take your vitamins. That's assuming a 100% transmission rate if interacting with someone with it. If you have a 10% transmission rate per interaction guess what that does to our number. This is starting to get to the point where you have higher odds of getting stuck by lighting than that interaction with a maskless person making a difference in whether you live or die vs them having had worn a mask.
