【Washington Times】Chinese researchers isolated deadly bat coronaviruses near Wuhan animal market

Chinese government researchers isolated more than 2,000 new viruses, including deadly bat coronaviruses, and carried out scientific work on them just three miles from a wild animal market identified as the epicenter of the COVID-19 pandemic.
Several Chinese state media outlets in recent months touted the virus research and lionized in particular a key researcher in Wuhan, Tian Junhua, as a leader in bat virus work.
......
A video posted online in December and funded by the Chinese government shows Mr. Tian inside caves in Hubei province taking samples from captured bats and storing them in vials.
......
Chinese officials have said the virus likely spread from wild animals to people at Wuhan’s Huanan Seafood Wholesale Market, not far from the Wuhan Centers for Disease Control and Prevention (CDC), the national center for China’s bat virus research.
......
Chinese officials refused to provide samples of its coronavirus strains to U.S. researchers shortly after the outbreak became public and did not allow international disease specialists to visit Wuhan for weeks.
Handling bats
The Chinese video “Youth in the Wild — Invisible Defender” records researchers engaged in casual handling of bats containing deadly viruses.
The seven-minute film boasts that China has “taken the lead” in global virus research and uncovered over 2,000 viruses in the past 12 years, the time since the outbreak of the bat-origin virus that causes severe acute respiratory syndrome (SARS).
The deadly virus behind the current pandemic is called SARS Coronavirus-2 and also has been traced to bats.
......
Chinese state media outlets revealed that Mr. Tian once failed to wear protective gear in a cave and as a result came into contact with bat urine. To avoid contracting a disease, he self-quarantined for 14 days — the same recommended period for people exposed to the new COVID-19 strain.
Mr. Tian works for the office of decontamination and biological disease vector prevention and control within the Wuhan CDC. According to a May 2017 report by the Wuhan Evening News, Mr. Tian has gathered thousands of bats for research work on bat viruses since 2012.
......
The researcher also has gathered viruses from ticks, mice and wasps.
After the incident exposing him to bat urine, Mr. Tian said, he kept a safe distance from his wife. “As long as I am not getting sick during the incubation period of 14 days, I can be lucky to get away with it,” he said.
The Wuhan report said the collection of research samples was difficult, dangerous and hard to fund.
Shenzhen News, a publication of the Guangdong Communist Youth League, described in December how Mr. Tian shuttled through caves and jungles looking for viruses in bats and ticks, called “vector organisms,” in the quest to develop vaccines. The report said the nearly 2,000 viruses discovered in China over the past 12 years nearly doubled the total number of known viruses.
A search of the Wuhan CDC website since the novel coronavirus outbreak contains no reference to Mr. Tian or his work. He has co-authored at least two scientific studies on the Wuhan virus and its impact.
