Chinese health authorities said there were 7,711 confirmed cases in the country as of 29 January.
Infections have also spread to at least 15 other countries.
The World Health Organization (WHO) are again meeting in Geneva to consider whether the virus should be declared a global health emergency.
Various countries have implemented evacuation and quarantine plans for nationals wanting to return from China, where the outbreak began in the city of Wuhan.
Russia has decided to close its 4,300km (2,670-mile) far-eastern border with China in an attempt to stop contagion.
WHO Director-General Tedros Adhanom Ghebreyesus named Germany, Vietnam and Japan, as places where people had caught the virus from others who had visited China.
“Although the numbers outside China are still relatively small, they hold the potential for a much larger outbreak,” he said, adding that human-to-human transmission was a concern.
More people have now been infected in China than during the Sars outbreak in the early 2000s, but the death toll remains far lower. Sars, also a coronavirus, caused acute respiratory illness.
Researchers are racing to develop a vaccine to protect people from the virus. One lab in California has plans for a potential vaccine to enter human trials by June or July.
What’s the latest on evacuations?
Voluntary evacuations of hundreds of foreign nationals from Wuhan are under way to help people who want to leave the closed-off city and return to their countries.
The UK, Australia, South Korea, Singapore and New Zealand are expected to quarantine all evacuees for two weeks to monitor them for symptoms and avoid any contagion.
