Mathematical models offer one form of clarity. When just 50% of the
population wears masks, say researchers simulating outbreaks, the share of
the population infected by the virus is cut in half. Once 80% of the
population wears a mask, it theoretically stops an outbreak in its tracks. &
ldquo;Any type of general mask use is likely to decrease viral exposure and
infection risk on a population level, despite imperfect fit and imperfect
adherence,” notes a 2008 study by the Netherland’s National
Institute for Public Health and the Environment.
