Covid cases and hospitalizations are rising again in the U.S., and deaths are starting to rise, too. In response, many people are understandably asking what the country can do to minimize the virus’s toll in the weeks ahead.
So far, a lot of discussion has focused on mask mandates. Schools in Philadelphia; Providence, R.I.; Berkeley, Calif.; and Brookline, Mass., have reimposed theirs, as have several colleges. Elsewhere, some people are frustrated that officials, like New York City’s mayor, Eric Adams, have not done so.
Critics have accused these leaders of a lack of political courage, saying that they are yielding to Covid fatigue rather than imposing necessary public health measures. But I think that the criticism misreads both the history of public health and the recent scientific evidence about mask mandates.
