95% masking would ‘effectively end this pandemic,’ says Dr. Vin Gupta

NBC News medical contributor Dr. Vin Gupta discusses new CDC guidelines that state masks will not only prevent the spread of COVID-19 but will also protect the mask wearer from contracting the virus. “We know that if there is 95% masking broadly in the United States, we would effectively end this pandemic, we wouldn’t have to worry about a vaccine, and we would save 100,000 lives by Jan. 31 of 2021,” said Dr. Gupta.
