Masks and social distancing work, new analysis finds

Masks and social distancing can help control the coronavirus but hand washing and other measures are still needed, a new analysis finds.

Researchers concluded single-layer cloth masks are less effective than surgical masks, while tight-fitting N95 masks provide the best protection. A distance of 1 meter (more than 3 feet) between people lowers the danger of catching the virus, while 2 meters (about 6 1/2 feet) is even better.
