But as more and more of the population is vaccinated, governments need to give Americans an off-ramp to the post-pandemic world. Ending outdoor mask mandates — or at the very least telling people when they can expect outdoor mask mandates to lift — is a good place to start, for a few reasons.
Requiring that people always wear masks when they leave home, and especially in places with low levels of viral transmission, is overkill. As mentioned, the coronavirus disperses outside, posing little risk to people who are walking alone or even swiftly passing by strangers. In fact, almost all of the documented cases of outdoor transmission have involved long conversations, or face-to-face yelling. The risk calculation changes if you’re standing in a crowd: Some uneven evidence suggests that the Black Lives Matter protests last summer increased local infections. But that’s an easy carve-out. States can end blanket mandates and still recommend outdoor masking by anyone experiencing symptoms, or in crowds. (Extended conversations pose their own risk, but when people are vaccinated, the odds of viral transmission are probably somewhere between microscopic and nonexistent.)
