A sharp fall in new deaths and cases of the coronavirus has been reported in China, but world health officials warn it is too early to make predictions about the outbreak as infections rise elsewhere.
Chinese authorities say the mainland had 397 new confirmed cases on Friday, down from 889 a day earlier.
The numbers surged elsewhere, though, with outbreaks worsening in South Korea, Iran, Italy and Lebanon.
In South Korea, authorities said on Saturday the number of new infections had doubled to 433, and suggested the tally could rise significantly as more than 1000 people who attended a church at the centre of the outbreak reported flu-like symptoms.
The World Health Organization welcomed the reported decline in new Chinese cases, but said it was concerned about the number of new infections elsewhere with no clear link to China such as travel history or contact with a confirmed case.
"Our biggest concern continues to be the potential for COVID-19 to spread in countries with weaker health systems," WHO chief Tedros Adhanom Ghebreyesus said.
The UN agency is calling for US$675 million to support most vulnerable countries, he said, adding 13 countries in Africa are seen as a priority because of their links to China.
In total, China has reported 76,396 cases to the WHO, and 2348 deaths.
According to available data, the disease remains mild in 80 percent of patients, and severe or critical in 20 percent. The virus has been fatal in two percent of reported cases.
The disease has spread to some 26 countries and territories outside mainland China, killing 13 people, according to a Reuters tally.
The latest Chinese figures showed only 31 of the new cases on Friday were outside of the virus epicentre of Hubei province, the lowest number since the National Health Commission started compiling nationwide data a month ago.
But new, albeit isolated, findings about the coronavirus could complicate efforts to thwart it, including the Hubei government's announcement on Saturday that an elderly man took 27 days to show symptoms after infection, almost twice the presumed 14-day incubation period.
That follows Chinese scientists reporting that a woman from Wuhan had travelled 675km and infected five relatives without showing signs of infection.
State television showed the arrival in Wuhan of the "blue whale" on Saturday, the first of seven river cruise ships being brought in to some of the tens of thousands of medical workers who have been sent to Hubei to contain the virus.
Social media users posted footage and images of some malls reopening, including in the cities of Wuxi, Hangzhou and in Gansu province.
Shoppers queued in near-empty streets outside for mandatory temperature checks as trickles of customers in masks perused luxury goods shops and makeup counters.
Iran, which had no reported cases earlier this week, has now detected 10 new cases of coronavirus, taking the number to 28 infections and five deaths.
Japan, which confirmed 14 new cases on Saturday, faces growing questions about whether it is doing enough to contain its outbreak and whether the virus could disrupt this year's Tokyo Olympics.
Organisers postponed the start of training for volunteers as a precaution.
