China stepped up measures to contain a virus which has killed 25 people and infected more than 800, with public transport suspensions in 10 cities, temples shutting, and the rapid construction of a new hospital to treat those infected.
The World Health Organisation (WHO) on Thursday declared the new coronavirus an emergency for China but stopped short of declaring the epidemic of international concern.
Health authorities fear the infection rate could accelerate over the Lunar New Year, when hundreds of millions of Chinese travel at home and abroad during week-long holidays, which began on Friday.
As of Thursday, there were 830 confirmed cases and 25 people had died, the National Health Commission. Most cases are in the central Chinese city of Wuhan, where the virus is believed to have originated in a market which traded in illegal wildlife.
