Studies have shown that masks significantly decrease the chances of transmitting or contracting the coronavirus. But not all masks provide equal protection. Depending on the fabric and number of layers, homemade and simple cloth masks have a range of effectiveness that can be as low as 26%, which leaves the wearer vulnerable.
Some experts like Brigham Women’s Hospital and Harvard Medical School physician Dr. Abraar Karan have been advocating for public use of N95 masks from the start of the pandemic. In an interview with CNN Chief Medical Correspondent Dr. Sanjay Gupta, Dr. Karan outlined why N95s are critical at this stage of the pandemic.
“If for four weeks the country essentially wore these masks in those risky settings like that indoors, what kind of difference do you think it would make?” Gupta asked.
“This would stop the epidemic,” Karan responded.
