BEIJING, CHINA - JANUARY 30: Passengers wear protective masks as they walk he their luggagein the arrivals area at Beijing Capital Airport on January 30, 2020 in Beijing, China. The number of cases of a deadly new coronavirus rose to over 7000 in mainland China Thursday as the country continued to lock down the city of Wuhan in an effort to contain the spread of the pneumonia-like disease which medicals experts have confirmed can be passed from human to human. In an unprecedented move, Chinese authorities put travel restrictions on the city which is the epicentre of the virus and neighbouring municipalities affecting tens of millions of people. The number of those who have died from the virus in China climbed to over 170 on Thursday, mostly in Hubei province, and cases have been reported in other countries including the United States, Canada, Australia, Japan, South Korea, and France. The World Health Organization has warned all governments to be on alert, and its emergency committee is to meet later on Thursday to decide whether to declare a global health emergency.

"Do not travel to China due to novel coronavirus first identified in Wuhan, China," the Level 4
states, noting that the World Health Organization declared the coronavirus a public health emergency of international concern earlier that day.
"Travelers should be prepared for travel restrictions to be put into effect with little or no advance notice. Commercial carriers have reduced or suspended routes to and from China," the alert notes stated. "Those currently in China should consider departing using commercial means."
The news comes after the US Centers for Disease Control and Prevention announced on Thursday that the husband of an Illinois woman with Wuhan coronavirus is now infected with the illness --
the first confirmed case of person-to-person transmission in the United States.
The number of cases of the virus, which has
killed at least 213 people , shot up to more than 8,100 in mainland China alone by Thursday evening. While the virus originated in the Chinese city of Wuhan in December, there are now more than 100 cases in 20 other countries and territories spanning Asia, North America, Europe and the Middle East. India and the Philippines were the latest countries to confirm the virus had reached their shores.
The department has
increasingly looked to dissuade American travel
to China in recent weeks in response to the outbreak. It raised the travel advisory on Monday from Level 2: Exercise Increased Caution to Level 3: Reconsider Travel due to the virus. Last week, the department raised the advisory to China's Hubei Province -- of which Wuhan is the provincial capital -- to Level 4.
