Concerns are mounting about how long the novel coronavirus may survive on surfaces - so much so that China's central bank has taken measures to deep clean and destroy its cash, which changes hands multiple times a day, in an effort to contain the virus.
Most people infected by the new coronavirus in China have mild symptoms, with older patients and those with underlying conditions most at risk from the disease, according to a study by Chinese researchers.
The report on the 45,000 cases by the Chinese Centre for Disease Control and Prevention prompted guarded optimism from health authorities. He says no travel ban has ever helped entirely block the entry of an epidemic in the past.
In about 14% of cases, the virus causes severe diseases including pneumonia and shortness of breath. Communist Party officials will meet on February 24 to deliberate on a postponement of the meeting due to start on March 5.
More than 80 percent of patients with the disease have mild symptoms and recover, the World Health Organization said.
Around half of all known cases of the virus outside China have been found aboard the Diamond Princess in Yokohama, where around 400 people have tested positive since the cruise liner was ordered to stay under quarantine off Japan on February 3.
There were no deaths among children aged up to nine, despite at least two cases of newborn babies infected through their mothers. Ordinary influenza has a fatality rate of 0.1% yet kills hundreds of thousands because it infects millions each year.
That risk is higher among those with other health problems - more than 10% for those with heart disease, for example, and higher among those in Hubei province versus elsewhere in China.
Wuhan has accounted for the vast majority of mainland China's 70,548 cases.
Attention was also turning to the Westerdam, a cruise ship in Cambodia, where numerous 2,200 people aboard passengers were allowed to disembark after all initially receiving a clean bill of health.
More than 300 American cruise liner passengers, including 14 who tested positive for coronavirus, were flown to military bases in the United States, after two weeks under quarantine off Japan.
One American passenger who disembarked in Cambodia tested positive for the virus in Malaysia on Saturday, but the company said none of the other 1,454 passengers and 802 crew had reported symptoms. Blood tests showed an over-activation of a type of infection-fighting cell that accounted for part of the severe immune injury he sustained, doctors at the Fifth Medical Center of PLA General Hospital in Beijing said in a study released on Sunday.
In Asia, with fears of the virus spreading further, Chinese and residents of nearby countries and territories have begun hoarding supplies of everything from masks and other personal protective gear to instant noodles, cooking oil and toilet paper. However, the CDC opines that this might not be the main way the virus spreads.
South Korean President Moon Jae-in said the economy was in an emergency situation and required stimulus as the epidemic had disrupted demand for South Korean goods.
Japan has 518 confirmed cases, including the 454 from the cruise ship, and one death from the virus.
