If I am the only person wearing a mask indoors in a store or elsewhere, am I completely safe from infection?
It’s true that masks work best when everyone in the room is wearing them. This is because when an infected person wears a mask, most of the exhaled infection particles are trapped, preventing the virus from spreading to its source. And if fewer virus particles were carried around the room, masks worn by other people would likely make survivors unable to survive.
But there is also ample evidence that masks protect consumers even when others around them are not wearing masks. The level of protection depends on the quality of the mask and its fit. For example, when a hotel in Switzerland broke down,
many employees and one guest who tested positive for the coronavirus wore only face shields (no masks); Whoever wears the mask is not infected. And a study in Tennessee found that communities with mandatory masks had fewer hospital stays than areas that didn’t require masks.
“Health care workers, scientists working with nasty pathogens, and workers exposed to harmful particulate matter in the air in the workplace rely on specialized masks like N95 for protection, so we know that a properly fitted high-performance mask works,” said Lincy, Professor of Engineering. Virginia Engineering. and one of the world’s leading experts on virus transmission.
Several laboratory studies have also documented that masks protect the wearer, although the level of that protection can vary depending on the type of mask, the material from which the mask is made, and the testing environment. and how particle exposure is measured.
