Does your mask need to cover your nose to be effective against coronavirus?

Masks have become a key weapon in the fight against the coronavirus, but they've also been a source of controversy in the US, even becoming a political issue. The Association of American Medical Colleges has come out with consensus guidance on facemasks, the "Do’s and Don’ts for Face Coverings," so we asked Dr. Atul Grover, Executive Director of AAMC Research and Action Institute to join KYW In Depth to break down how and when they should be worn, what you should look for in an effective mask, and most importantly, just how important your mask is in the fight against COVID-19.
