Why Masks Work, but Mandates Haven't

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.

The evidence suggests that broad mask mandates have not done much to reduce Covid caseloads over the past two years. Today, mask rules may do even less than in the past, given the contagiousness of current versions of the virus. And successful public health campaigns rarely involve a divisive fight over a measure unlikely to make a big difference."

1. Clearly an evolving situation with vaccines and prior infection conferring some protection

However, i recall a study out of Kansas earlier showing an lower infection rate in counties that had mask mandates.
