Mainland China had 397 new confirmed cases of coronavirus infections on Friday, down from 889 a day earlier, but only 31 cases 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 infection numbers continued to rise elsewhere, with outbreaks worsening in South Korea, Italy and Lebanon and Iran, prompting a warning from the World Health Organization that the window of opportunity to contain the international spread was closing..
South Korea saw another spike in infections, with 229 new confirmed cases, taking its tally to 433. Officials warned that could rise substantially as more than 1,000 people who attended a church at the centre of the outbreak had shown flu-like symptoms.
Iran, which had no reported cases earlier this week, saw 10 new cases, one of which had died, taking the number to 28 infections and five deaths.

On Friday, he said now was the time to act decisively.
"We still have a chance to contain it," he said. "If we don't, if we squander the opportunity, then there will be a serious problem on our hands."

The total number of confirmed cases in mainland China rose to 76,288, with the death toll at 2,345 as of the end of Friday. Hubei reported 106 new deaths, of which 90 were in Wuhan.
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 400 miles (675km) and infected five relatives without showing signs of infection, offering new evidence of asymptomatical spreading.

Some analysts believe China's economy could contract in the first quarter from the previous three months due to the combined supply and demand shocks caused by the epidemic and strict government containment measures. On an annual basis, some warn growth could fall by as much as half from 6% in the fourth quarter.
However, transport restrictions remain in many areas and while more firms are reopening, the limited data available suggests manufacturing is still at weak levels, with disruptions starting to spillover into global supply chains.
