Masks Blocked Covid-19 at Hair Salon

(p. A6) Vigilant mask wearing might have spared nearly 140 people from catching the coronavirus at a hair salon in Missouri, according to a report published on Tuesday [July 14, 2020] by the Centers for Disease Control and Prevention. In May [2020], the people interacted with two hair stylists with confirmed coronavirus infections, but none ended up showing symptoms of Covid-19.

. . .

But policies instructing locals to cover their mouths and noses, put in place by the city of Springfield and by the salon where the stylists worked, Great Clips, appear to have played a substantial role in curbing the spread of disease.
