On 31 December 2019, WHO was alerted to several cases of pneumonia in Wuhan City, Hubei Province of China. The virus did not match any other known virus. This raised concern because when a virus is new, we do not know how it affects people.
One week later, on 7 January, Chinese authorities confirmed that they had identified a new virus. The new virus is a coronavirus, which is a family of viruses that include the common cold, and viruses such as SARS and MERS. This new virus was temporarily named “2019-nCoV.”
WHO has been working with Chinese authorities and global experts from the day we were informed, to learn more about the virus, how it affects the people who are sick with it, how they can be treated, and what countries can do to respond.
Because this is a coronavirus, which usually causes respiratory illness, WHO has advice to people on how to protect themselves and those around them from getting the disease.
