Virus peaking, says senior Chinese doctor

Zhong Nanshan's previous forecast of an earlier peak proved to be premature.

The coronavirus outbreak is hitting a peak in China this month and may be over by April, the government's senior medical adviser says in the latest assessment of an epidemic that has rattled the world.

Zhong Nanshan, an 83-year-old epidemiologist who won fame for combating the SARS epidemic in 2003, shed tears about the doctor Li Wenliang who died last week after being reprimanded for raising the alarm.

But Zhong was optimistic on Tuesday the new outbreak would soon slow, with the number of new cases already declining in some places.

The peak should come in the middle or late February, followed by a plateau and decrease, Zhong said, basing the forecast on mathematical modelling, recent events and government action.

"I hope this outbreak or this event may be over in something like April," he said in a hospital run by Guangzhou Medical University, where 11 coronavirus patients were being treated.

Though his comments may soothe some global anxiety over the coronavirus - which has killed more than 1000 people and seen more than 40,000 cases, almost all in China - Zhong's previous forecast of an earlier peak proved to be premature.

"We don't know why it's so contagious, so that's a big problem," added Zhong, who helped identify flaws in China's emergency response systems during the 2002-03 SARS crisis.

He said there was a gradual reduction in new cases in the southern province of Guangdong where he was, and also in Zhejiang and elsewhere.

"So that's good news for us."

With China taking unprecedented measures to seal infected regions and limit transmission routes, Zhong applauded the government for locking down Wuhan, the city at the epicentre which he said lost control of the virus at an early stage.

"The local government, local healthcare authority should have some responsibility on this," he said.

"Their work had not been done well."

The virus is believed to have originated in a seafood market in Wuhan in early December.

Authorities have also come under fire for their heavy-handed treatment of Dr Li, who was detained for publicising the disease before becoming its best-known fatality last Friday.
