The virus, which causes a disease called COVID-19, can infect the nose, throat, and sinuses. A recent study from the Chinese Center for Disease Control found that around 80% of coronavirus cases in China have been mild.

Airports around the world are screening passengers for the virus and many countries have evacuated citizens and employees from China.
