“Adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results.”
You can’t eat or drink through a mask. It’s no wonder they were twice as likely to test positive.
How do you stop people touching their virus/bacteria/germ trap and then touching other things that others then touch? You may be limiting the distance droplets travel while your mask is new, but you are collecting growing colonies of all kinds of germs in your mask and eventually delivering them with your hands and moist breath.
A Centers for Disease Control report released in September shows that masks and face coverings are not effective in preventing the spread of COVID-19, even for those people who consistently wear them.
