The World Health Organization has said foreign nationals should not be evacuated from China as countries rush to airlift their citizens to protect them from the novel coronavirus outbreak.
Airlines have also cancelling flights and adjusting schedules as a growing number of countries raise travel warnings to not just Hubei province where the new coronavirus broke out, but also to the rest of mainland China.
The 2019 Novel Coronavirus which is similar to the SARS pathogen has claimed at least 100 lives since emerging in a market in the central Chinese city of Wuhan, and spread around the world.

China extends its week-long holiday by an extra three days to February 2 to help stem the coronavirus epidemic, as authorities announced that 2,744 people had fallen ill and at least 80 had died.
Small numbers of cases also have been found in Thailand, Taiwan, Japan, South Korea, the US, Vietnam, Singapore, Malaysia, Nepal, France and Australia.
