The Wuhan coronavirus has killed 9 people and infected 440 people across mainland China, according to China’s National Health Commission Minister, Li Bin.

At a press conference in Beijing on Wednesday, officials said there is a possibility for the virus to mutate, but did not give any details on what those mutations could be when asked for details.

The Wuhan Coronavirus has reached 5 countries, including the United States with a case found in Washington state. Worldwide, 446 people have now been infected.

A third case has been confirmed in Thailand, said Li in Beijing on Wednesday.

The three new deaths were all in Wuhan in Hubei province where the virus is believed to have originated, Li added. The virus has now spread to 12 provinces and municipalities within mainland China.

Outside of mainland China there has now been 3 cases confirmed in Thailand, 1 case on the island of Taiwan, 1 case in South Korea, 1 case in Japan, and 1 case in the United States.
