Sheldon Jacobson: We need clear and sensible information about when to wear a face mask

The CDC guidelines on community risk (which effectively provides guidance on when to wear a face mask in public venues) focuses on new infection rates, hospitalization admissions, and hospital bed availability, making them reactive. The current uptick of infections with the new omicron variant, BA.2, has been slow to produce many severe cases. This means that around 90% of counties are labeled low risk, with under 1% of counties labeled high risk.
