World Health Organization investigators looking for clues into the origin of the coronavirus in the central Chinese city of Wuhan said that the Chinese side has provided a high level of cooperation, but cautioned against expecting immediate results from the visit.
“I keep saying that we need to be realistic, a short mission like this one will not have all the answers but it helps advance the understanding of the #virusorigin #wuhan," Hung Nguyen-Viet, co-leader of the Animal and Human Health Program of the International Livestock Research Institute in Nairobi, Kenya, said in a tweet Thursday.
In an earlier tweet, zoologist and team member Peter Daszak praised Wednesday’s meetings with staff at the key Wuhan Institute of Virology, including with Deputy Director is Shi Zhengli, a virologist who worked with Daszak to track down the origins of SARS that originated in China and led to the 2003 outbreak.
“Extremely important meeting today with staff at WIV including Dr Shi Zhengli. Frank, open discussion. Key questions asked & answered.,” Daszak tweeted.
The team on Thursday spent around two hours meetings with managers and residents at the Jiangxinyuan community administrative center in Wuhan's Hanyang District. No details were given.
Official statistics shows that there were at least 16 confirmed COVID-19 cases in the community last year among nearly 10,000 people living there when the virus broke out.
Earlier, Daszak tweeted images of media outside the virology institute, saying: “Thanking the press for their patience and interest in getting this news out to the world. The work is moving ahead & we look forward to being able to talk about the results as soon as possible."
The Wuhan Institute of Virology has collected extensive virus samples, leading to unproven allegations that it may have caused the original outbreak by leaking the virus into the surrounding community. China has strongly denied that possibility and has promoted unproven theories that the virus may have originated elsewhere.
Along with the institute, the WHO team that includes experts from 10 nations has visited hospitals, research institutes, a traditional market tied to the outbreak and other sites.
Members of the team have met with institute researchers and management, experts, vendors, residents and media representatives, the spokesperson for China's National Health Commission, Mi Feng, told reporters at a briefing Thursday.
It is likely to take years and multiple investigations in many parts of the globe to confirm the origins of the virus because of the exhaustive research, including taking animal samples, genetic analysis and epidemiological studies required to pin down an outbreak’s animal reservoir. One possibility is that a wildlife poacher might have passed the virus to traders who carried it to Wuhan but that has yet to be proven.
The first clusters of COVID-19 were detected in Wuhan in late 2019, prompting the government to put the city of 11 million under a strict 76-day lockdown. China has since reported more than 89,000 cases and 4,600 deaths — the bulk of them in Wuhan — with new cases largely concentrated in its northeast and local lockdowns and travel restrictions being imposed to contain the outbreaks.
New cases of local transmission fell to just 17 on Thursday as Chinese heed government calls to skip family visits and stay put during the Lunar New Year holiday later this month.
China has also pushed ahead with a plan to vaccinate 50 million people for COVID-19 by the middle of this month. As of Wednesday, more than 31 million doses had been administered, Mi told reporters.
