New data from the Centers for Disease Control and Prevention (CDC) reported Friday emphasizes the importance of wearing the right mask while in a high-risk setting.
According to the data, surgical masks reduce the risk of testing positive for COVID-19 by 66 percent. More effective masks, like N95 and KN95 masks, decrease the risk of infection by 83 percent. A KN95 filters 95 percent of particles, and so does an N95. A KF94 filters 94 percent of particles. The difference between the letters is the government standard certification.
