Health expert Dr. Atul Gawande told CNBC on Monday that people must take seriously the responsibility of wearing a face mask to prevent the spread of the coronavirus.
Gawande told CNBC, “If we can get over 60% of us wearing masks that are 60% effective ... we can shut down the virus."
The Brigham and Women’s Hospital surgeon and Harvard University professor, said a double-layered, well-fitted cotton mask would be at least 60% effective at blocking a person’s respiratory droplets, which is how the virus is transmitted.
In early April, the Centers for Disease Control began to recommend that people wear face coverings, particularly in settings where social distancing can be more difficult, such as in the grocery store.
Gawande said he has so far been impressed with the number of people he sees in public wearing masks. But he said it has varied community by community.
