Walk around any crowded area during flu season and you'll see people wearing medical face masks to protect themselves from germs and other contaminants. With the rapid spread of the coronavirus that causes COVID-19 and increased concerns about a US outbreak, face masks have flown off store shelves. But do they really work?
The number of novel coronavirus (a.k.a. COVID-19) cases continues to climb. More than 160,000 illnesses have been identified worldwide, while more than 6,000 deaths have been reported, per the most recent data from the World Health Organization (WHO). While a majority of these cases stem out of China, the Centers for Disease Control and Prevention (CDC) has also confirmed multiple cases within the United States.
