The ability of the coronavirus to spread is getting stronger and infections could continue to rise, China's National Health Commission said on Sunday, with more than 2,000 people globally infected and 56 in China killed by the disease.
National Health Commission Minister Ma Xiaowei, speaking at a press briefing, said knowledge of the virus was limited.
Ma said the incubation period for the coronavirus can range from one to 14 days, and that the virus is infectious during incubation, which was not the case with Severe Acute Respiratory Syndrome (SARS), a coronavirus that originated in China and killed nearly 800 people globally in 2002 and 2003.
Containment efforts, which have thus far included transportation and travel curbs and the cancellation of big events, will be intensified, Ma told a crowded news briefing on the second day of the Lunar New Year holiday.
The virus, believed to have originated late last year in a seafood market in the central Chinese city of Wuhan that was illegally selling wildlife, has spread to Chinese cities including Beijing and Shanghai, as well as the United States, Thailand, South Korea, Japan, Australia, France and Canada.
President Xi Jinping said during a politburo meeting on Saturday that China was facing a "grave situation", as health authorities around the world scrambled to prevent a pandemic.
On Sunday, China announced a nationwide ban on the sale of wildlife in markets, restaurants, and e-commerce platforms. Wild and often poached animals packed together in Chinese markets are blamed as incubators for viruses to evolve and jump the species barrier to humans.
Snakes, peacocks, crocodiles and other species can also be found for sale via Taobao, an e-commerce website run by Alibaba.
The U.S. State Department said it will relocate personnel at its Wuhan consulate to the United States and will offer a limited number of seats to private U.S. citizens on a Jan. 28 flight to San Francisco.
The World Health Organisation this week stopped short of calling the outbreak a global health emergency, but some health experts question whether China can continue to contain the epidemic.
On Sunday, China confirmed 1,975 cases of patients infected with the new coronavirus as of Jan. 25, while the death toll from the virus has risen to 56, state broadcaster CCTV reported.
The outbreak has prompted widening curbs on movements within China, with Wuhan, a city of 11 million, on virtual lockdown, with transports links all-but severed except for emergency vehicles.
Health authorities in Beijing urged people not to shake hands but instead salute using a traditional cupped-hand gesture. The advice was sent in a text message that went out to mobile phone users in the city on Sunday morning.
CANCELLATIONS AND MISTRUST
China has called for transparency in managing the crisis, after a cover-up of the spread of the deadly SARS virus eroded public trust, but officials in Wuhan have been criticised for their handling of the current outbreak.
"People in my hometown all suspect the real infected patients number given by authorities," said Violet Li, who lives in the Wuhan district where the seafood market is located.
"I go out with a mask twice a day to walk the dog - that's the only outdoor activity," she told Reuters by text message.
The outbreak has overshadowed the start of the Lunar New Year, when hundreds of millions of Chinese travel at home and abroad to be with families, with public events cancelled and many tourist sites shut.
Many cinemas across China are also closed with major film premieres postponed, slashing revenues. Theatres in the country took in just 1.81 million yuan ($262,167) from tickets on Saturday, a tiny fraction of the 1.46 billion yuan on the Lunar New Year Day in 2019, according to data from movie-ticketing company Maoyan.
Cruise operators including Royal Caribbean Cruises, Costa Cruises, MSC Cruises and Astro Ocean Cruises said that they cancelled a combined 12 cruises that had been scheduled to embark from Chinese ports before February 2.
The newly identified coronavirus has created alarm because there are still many unknowns surrounding it, such as how dangerous it is and how easily it spreads between people. It can cause pneumonia, which has been deadly in some cases.
VIRUS SPREADING OUTSIDE CHINA
On Saturday, Hong Kong declared a virus emergency, scrapped celebrations and restricted links to mainland China.
Hong Kong Disneyland and the city's Ocean Park theme park were closed on Sunday. Shanghai Disneyland, which expected 100,000 visitors daily through the Lunar New Year holidays, has already closed.
In Hong Kong, with five confirmed cases, the city's leader Carrie Lam said on Saturday that flights and high speed rail trips between the city and Wuhan will be halted. Schools in Hong Kong that are currently on Lunar New Year holidays will remain closed until Feb. 17.
On Saturday, Canada declared the first "presumptive" confirmed case of the virus in a resident who had returned from Wuhan. Australia confirmed its first four cases on Saturday, Malaysia confirmed four and France reported Europe's first cases on Friday.
Airports around the world have stepped up screening of passengers from China, although some health officials and experts have questioned the effectiveness of such screenings.
In an illustration of how such efforts could miss cases, doctors at a Paris hospital said two of the three Chinese nationals in France who have been diagnosed with the virus had arrived in the country without showing any symptoms.
A report by infectious disease specialists at Imperial College, London on Saturday said the epidemic "represents a clear and ongoing global health threat," adding: "It is uncertain at the current time whether it is possible to contain the continuing epidemic within China."
