As the coronavirus epidemic infected about 11,000 people and killed 258, according to figures released Saturday, Singapore and Mongolia have imposed sweeping bans on arrivals by land, sea or air from China.
The United States also slammed a total travel ban to China on its citizens.
The US State Department raised its warning alert to the highest level, telling Americans “do not travel” to China and urged those already there to leave.
The death toll from China’s coronavirus outbreak has surpassed 250, the government said Saturday.
At least 258 people have died and more than 11,000 people have been infected in China by the new coronavirus, according to new figures from officials in hard-hit Hubei province.
With countries around the world growing increasingly concerned, the World Health Organization, which was criticised for initially downplaying the virus threat, declared the outbreak a global health emergency on Thursday.
