The United States has confirmed the first case of the new coronavirus on its territory.

The Centers for Disease Control said the virus, which originated in China, had been diagnosed in a traveller who arrived in Seattle from China.

The virus, which spread from the Chinese city of Wuhan, has infected almost 300 people, and six have died.

North Korea has temporarily closed its borders to foreign tourists in response to the threat.

The CDC says the patient diagnosed in the US returned from Wuhan on 15 January..

Chinese authorities have confirmed more than 200 people have caught the coronavirus, which can cause a type of pneumonia that has killed four people in the central city of Wuhan.

The virus - which can pass from person to person - broke out in Wuhan but four cases have been reported in Thailand, Japan and South Korea, raising concerns about its spread through international air travel.
