The death toll from the virus in mainland China jumped by 73 to 563, with more than 28,000 confirmed infections there.
"Urgent support is needed to bolster weak health systems to detect, diagnose and care for people with the virus", Director General Tedros Adhanom Ghebreyesus said in a statement on Wednesday. The hospital wrote: "We deeply regret and mourn for his death". "We are here waiting for a miracle".

The Wuhan police launched an investigation against Li about "spreading gossip" after the post.
Yu took Air China as an example, noting that the carrier is applying to open global multi-stop flights to pick up more passengers, which could be a good choice at such a hard time.
Wednesday's news contrasts with that of a healthy baby who was born to a coronavirus-infected mother while in quarantine last week.
The child was born healthy on January 13, but developed coronavirus symptoms on January 29, after the baby's nanny and mother both contracted the disease.
Early reports of Dr Li's death, before the hospital said he was still alive, set off an outpouring of messages on the Chinese internet that lionised him as a hero who stood up to officials trying to play down a medical threat that came to engulf Wuhan, spill across China and ignite an global health crisis.

In Canada, a British Columbia health official announced two new presumptive cases of coronavirus. White House economic adviser Larry Kudlow said the epidemic would delay a surge in US exports to China expected from a Phase 1 trade deal set to take effect this month.
Both are connected to the second presumptive case of coronavirus found in the Vancouver Coastal Health region that was announced on Tuesday.
