Why do we wear masks? Because we know people can spread the virus when they have no symptoms. Here's a good example: 640 army recruits arrive for training at Ft Benning, GA; Four of them test positive so everyone goes in quarantine for 2 weeks... keep reading this thread... 1/6
They let the recruits out of quarantine so assumedly nobody had symptoms. But at least one person in that group got infected during quarantine and was not showing symptoms, because 8 days later someone reported with COVID symptoms. That's 14+8=22 days after testing... 2/6
Reminder: it's usually 5 days from infection until a person gets symptoms, it's usually 4 days between a person getting infected and the virus starting to shed so that person can infect someone else, and half of people never show symptoms but can still infect others... 3/6
So probably there were a couple of generations of infection in that group, with some recruits infecting others and none of them having symptoms and reporting it. So here we are 22 days later, they retested all 640 recruits. How many infected do you think they find?... 4/6
ONE HUNDRED FORTY TWO!!! That's 22% of the group! Now either there's just one or two generations of asymptomatic spread, and then one super-spreader gets loads of people sick, or there are many generations of silent spread slowly growing through the group... 5/6
In conclusion, wear a f'ing mask!! You can never know if you're infected and without symptoms. By wearing a mask you protect your elderly aunt and your best friend's diabetic uncle from catching your infection you never knew you had. 6/6 Article here: https://connectingvets.radio.com/articles/fort-benning-confirms-142-covid-19-cases-in-2-battalions
