The coronavirus outbreak that began in Wuhan, the capital of China's central province of Hubei, has killed 170 people in the country and infected more than 7,800 globally, most of them in China.

The virus has caused alarm because it is still too early to know how dangerous it is and how easily it spreads among people.

Chinese officials say it is infectious during its incubation period, which could range from one to 14 days.

Here is what we know:

  • The death toll in China has risen to 170,with 162 in Hubei, authorities said. Another 7,711 people in China have been infected.
  • There are more than 100 confirmed cases of infection outside mainland China. The counties involved include Thailand, Japan, Hong Kong, Singapore, Taiwan, Australia, Malaysia, the United States, France, South Korea, the United Arab Emirates, Germany, Canada, Vietnam, Nepal, Cambodia, Sri Lanka, Finland and the Philippines.
  • No deaths have been reported outside China.
  • The previously unknown coronavirus strain is believed to have emerged late last year from illegally traded wildlife at a market in Wuhan, a city of 11 million.
  • The World Health Organisation will meet today to decide whether its rapid spread amounts to a global health emergency.
  • Several Chinese cities have levied strict travel curbs.
  • Global airlines have suspended or scaled back direct flights to China's major cities.
  • Countries including Australia, Canada, France, Germany, Indonesia, Italy, Japan, Singapore, South Korea and the United States are working to evacuate citizens from Wuhan or have already started.
  • Nearly 200 evacuated Americans arrived at a US military base in California to be isolated for at least 72 hours.

  • The World Athletics Indoor Championships scheduled for the Chinese city of Nanjing in March have been postponed until 2021.
  • Google and IKEA said they were temporarily shutting all offices and stores in China over the outbreak.
