Chinese authorities have reported 139 new cases in Wuhan in last two days, taking the total number of confirmed cases in there to 198. Numerous initial patients had worked or shopped at the city's Huanan Seafood Wholesale Market, at which vendors also sold live birds and other animals, suggesting the infection was jumping from animals to humans.
This brings the total number of known cases worldwide to more than 200, underscoring the challenge for health authorities seeking to contain the outbreak.
No human-to-human transmission has been confirmed yet, but health officials have not ruled out the possibility. One of them died on January 18, the third death reported in the city.
A Chinese health official said today that 14 healthcare workers have been infected with the Wuhan-linked novel coronavirus (2019-nCoV), bolstering evidence of human-to-human spread and spurring new questions about virus circulation against a backdrop of other winter respiratory illnesses.
Since hundreds of people who came into close contact with diagnosed patients have not gotten sick, the municipal health commission maintains that the virus is not easily transmitted between humans.
The new cases, the first inside China outside the central city of Wuhan where the virus was first reported, come as the country gears up for the Lunar New Year holidays later this week, when hundreds of millions of Chinese travel domestically and overseas.
Chinese President Xi Jingping spoke publicly of the outbreak for the first time Monday, urging the government to do everything possible to control spread of the virus.
They should "ensure that the masses have a quiet, peaceful and joyous Spring Festival", he added.
The new numbers rolled in just as Canadian and US health authorities both began screening passengers from Wuhan at three of each country's biggest airports.
Similarly, WHO confirmed that the infected patient in South Korea did not visit markets in Wuhan or have contact with animals or other confirmed cases.

"Watching the news, I do feel a little anxious".
However, two patients in southern China confirmed to have the virus over the weekend have not visited Wuhan city, where the outbreak is centred. The Beijing patients are receiving medical treatment in Daxing District.
In the southern Guangdong province which borders Hong Kong, the health commission confirmed one case.
"I think during this (holiday), we're not going to go out too much, and probably won't go to places with a lot of people, like the movie theatre".
Authorities around the globe, including in the United States and many Asian countries, have stepped up screening of travellers from Wuhan.
