The CDC recommends mask wearing, both to protect you from others and to protect them from you:
CDC recommends that people wear masks in public settings, like on public and mass transportation, at events and gatherings, and anywhere they will be around other people. Note that the CDC does not know at this time whether face shields are effective: https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/about-face-coverings.html Same page at the CDC web site has advice on choosing a mask. –Eric N > On Nov 24, 2020, at 1:25 AM, Sky Coulter <incommontr...@gmail.com> wrote: > > > I haven’t found a simple mask that doesn’t fog my glasses to some degree or > other.
