The reason for masks is that upwards of 40% of those positive for the Rona are asymptomatic but they are ABSOLUTELY infectious for upwards of ten days producing millions of airborne particles simply by breathing.

The data on whether "asymptomatic" spreading is occurring is still more speculative than definitive from what I've seen. One of the big points of contention is determining the difference between someone who is "asymptomatic" versus someone who has recently been infected but hasn't shown symptoms yet, but then does after 5 days or more. The concept of the asymptomatic person being some sort of superspreader without a mask is being seized upon by those who want to justify ridiculous levels of mask mandates, but has not been proven.

This was not spread by some asymptomatic person ANYONE with a viral load this large to infect all these people would not have been able to pass the testing procedures to get into the WH!! This virus was brought into the event in an aerosol bottle!!

Pre symptomatics are at their peak of infectious transmission before they show signs of infection a Korean study confirmed that via viral loads in the upper respiratory tract. Masks work on a mass scale Japan, Vietnam, Korea are all quantifiable examples of that. Japan never locked down despite having population density that exceeds NYC in nearly every Japanese city. The key difference is Japan has a mandatory mask use at all times everywhere. And it is part of their culture to use masks every flu season and any time they have so much as a sniffles the person masks up out of respect for their countrymen. I have been to Japan in early winter during peak flu season a few times and every time you see hundreds of people with masks they are an expected part of the flu season.
