As the Wuhan coronavirus continues to spread, officials in China are urging citizens to wear masks in public to stop the spread of the virus - and cities in China as well as other parts of Asia are reportedly running out of face masks. But can a mask really keep you from catching the virus?
A rapidly evolving health story broke in late December when a novel illness originating in Wuhan, China made the news. Reports of the number of infected people swiftly rose, and isolated cases of this new coronavirus - dubbed 2019-nCoV by scientists - have appeared in several countries due to international travel.
Common symptoms: coughing, fever, and shortness of breath. Non-respiratory symptoms (feeling nauseous, vomiting having diarrhea) were also reported. The virus is more violent with the elderly, the very young and with individuals that have a weak immune system. The majority of those infected however recover after a few days.
