Asian nations have sealed borders and clamped down on Chinese visitors as they try to protect themselves from a deadly virus epidemic.
The outbreak has killed some 130 people in China, sickened nearly 6,000 and sparked progressively more urgent precautions around the region.
Here are some key measures taken outside mainland China:
Papua New Guinea
The impoverished island nation shut air and seaports Wednesday to all foreign travellers coming from Asia.
The ministry of immigration also announced that Papua New Guinea's only official land border - with Indonesian-controlled Papua province - would be shut from Thursday.
Papua New Guinea residents returning from Asian countries will be held in quarantine for 14 days.
Mongolia
Mongolia has closed its border crossings with China to cars, temporarily shut schools and suspended all public events.
The measures announced Monday by the vast, landlocked country are some of the most drastic steps taken by any nation so far.
North Korea
Plans to ban foreign tourists were announced on 22 January as the already isolated nation sought to protect against the virus.
Pyongyang has taken similar actions in the past - it closed its borders to foreign tourists for more than four months from October 2014 in a bid to keep out the Ebola virus, even though no cases had been reported in Asia.
Singapore
Singapore announced Tuesday it will ban visitors who have travelled to Hubei as well as those with passports issued in that Chinese province.
Officials said efforts are also underway to track down an estimated 2,000 people already in Singapore with a Hubei travel history for potential quarantine.
Malaysia
Visitors from the Chinese city of Wuhan and its surrounding Hubei province have been banned since Monday.
Authorities have temporarily halted all issuance of visas for Chinese citizens from the hard-hit areas.
Philippines
Visa-on-arrival privileges for Chinese were suspended Tuesday to slow down the entry of Chinese tourists, while Filipinos were advised to avoid non-essential travel to China.
Charter flights between Wuhan, the Hubei city where the virus is suspected to have originated, and the Philippine island of resort of Boracay are suspended.
Macau
All staff in the city's bustling casinos were ordered from 22 January to wear face masks.
The former Portuguese colony is a huge draw for mainland tourists as the only place in China that allows gambling.
All arriving passengers from the mainland are also ordered to fill out health declaration forms.
Hong Kong
Six of the territory's 14 mainland crossings were to be sealed from Thursday as the city took steps to cut the number of people entering.
Visitors from ground-zero central Chinese province Hubei, as well as people who have visited the area, are banned from entering Hong Kong.
Sports centres, grounds, swimming pools, beaches, campsites and sites including museums were all to close, authorities said Tuesday. - AFP
