The deadly coronavirus that originated in Wuhan, China, has now spread to every region of the country.

China's National Health Commission confirmed a case of the virus in the southwestern frontier region of Tibet on Thursday. Tibet is the last of China's 34 regions to see someone infected by 2019-nCoV.

The death toll is still climbing. As of Thursday at least 170 people had died of the virus, all of them in China.

There are now 7,711 confirmed cases of infection on the Chinese mainland, with 10 in Hong Kong, seven in Macau, and eight in Taiwan.

The deadly coronavirus that originated in Wuhan, China, has officially spread to every region of the country.

Cases of the Wuhan coronavirus, officially called 2019 n-CoV, have been confirmed in all 34 of China's major regions, after the National Health Commission said Thursday that a person in the southwestern frontier region of Tibet had contracted the disease.

There are now 7,711 confirmed cases on the Chinese mainland, with 10 in Hong Kong, seven in Macau, and eight in Taiwan.

As of Thursday at least 170 people had died from the virus, all of them in China.

The virus, which originated in the central city of Wuhan in early December, has spread rapidly in the past few weeks.

There are confirmed cases in Qinghai, Xinjiang, and Tibet, the three most remote regions in the country.

The coronavirus had remained largely in Wuhan, its province Hubei, and other surrounding provinces in central China. Of the confirmed cases of the virus, more than 4,500 — or about 60% — are in Hubei province.

But it has spread rapidly over the past two weeks thanks in part to the mass travel carried out by millions of citizens in the run-up to the Lunar New Year, which took place Saturday.

On Wednesday, the NHC confirmed that the number of confirmed cases of the Wuhan coronavirus in mainland China officially eclipsed the number of SARS cases in the mainland during its 2002-2003 outbreak.

The number of SARS cases on the mainland topped out at 5,327, though there were close to 8,100 cases of SARS globally during the epidemic.

China is taking aggressive measures to try to prevent the virus from spreading, including quarantining Wuhan and many other cities in Hubei province and seeking to build two new hospitals in Wuhan in under a week.
