The head of the World Health Organization has warned that confirmed cases of coronavirus being transmitted by people who have never travelled to China could be the “tip of the iceberg”.
Tedros Adhanom Ghebreyesus’s remarks come as members of a WHO-led “international expert mission” flew to China yesterday to help coordinate a response to the outbreak.
The death toll from the epidemic rose to 908, all but two in mainland China, on Sunday as 97 more fatalities were recorded - the largest number in a single day since the virus was detected in the city of Wuhan in December.
Across mainland China, 3,062 new infections were confirmed on Sunday, bringing the total number to 40,171, according to the National Health Commission (NHC).
“There’ve been some concerning instances of onward #2019nCoV spread from people with no travel history to (China),” Tedros tweeted Sunday, using the virus’s provisional scientific name.
“The detection of a small number of cases may indicate more widespread transmission in other countries; in short, we may only be seeing the tip of the iceberg.”
While the spread of the virus outside China appeared to be slow, Tedros warned it could accelerate.
“Containment remains our objective, but all countries must use the window of opportunity created by the containment strategy to prepare for the virus’s possible arrival,” he said.
Outside mainland China, there have been more than 350 infections reported in nearly 30 places. There have been two deaths, one in the Philippines and the other in Hong Kong.
Several countries have banned arrivals from China while major airlines have suspended flights, and Air China cancelled some of its flights to the United States.
The WHO-led mission to China is being headed up by Bruce Aylward, a veteran of previous health emergencies, Tedros said. Aylward oversaw the WHO’s 2014-2016 response to the Ebola epidemic in West Africa.
The WHO said in recent days there had been “some stabilising” in the numbers of new cases of the coronavirus in China. But the UN agency cautioned it was too early to say if the virus had peaked.
The SARS-like virus is believed to have emerged late last year in the central city of Wuhan, the capital of Hubei province where millions of people are under lockdown in a bid to stop it spreading.
