The 2019 novel coronavirus causes COVID-19, a pneumonia-like disease with symptoms including fever, cough and shortness of breath. In some cases, it can lead to lung damage and can be fatal. 

Because the disease is thought mainly to pass through close contact with an infected person, health experts have recommended social distancing to slow its spread. The federal Centers for Disease Control recommends people stay at least six feet from each other and wear face masks while in public.
