It follows the US decision to declare a public health emergency and deny entry to foreign nationals who had visited China in the past two weeks.
There are more than 17,000 confirmed cases of the virus in China. Some 361 people have died there.
Outside China, there are more than 150 confirmed cases of the virus – and one death, in the Philippines.

On 30 January, the World Health Organization (WHO) declared a global health emergency over the new virus.
Following this, the US ordered the departure of all US personnel family members under the age of 21 in China.
Any US citizen who has been in Hubei province will be subject to 14 days’ quarantine upon returning to the US.
