In the United States, face masks are required in more and more places as part of the fight against the coronavirus. Many stores require them. Some governors are telling people they must wear a mask, even outdoors. Some journalists love scolding pedestrians and politicians who don’t wear them.

Meanwhile, the World Health Organization, which has generally been incompetent during this outbreak, possibly because of the organization’s coziness with the Chinese regime, is giving very different advice. Basically, the WHO says asymptomatic people shouldn’t wear masks in most cases.
