A prominent scientist on Sunday added his voice to the growing number of experts calling for a full investigation into the origins of the novel coronavirus, saying the future of public health is at stake.
New reports suggest that China’s Wuhan Institute of Virology was at the center of the outbreak, not animal-to-human transmission elsewhere in Wuhan, which was the long-prevalent opinion. President Biden last week ordered a fresh 90-day intelligence review of the virus’s origins with the goal of examining the possibility that it accidentally leaked from the Wuhan lab instead of being spread by bats or other animals to humans in a zoonotic transmission.
The White House wants a deeper understanding of how a virus that has killed about 600,000 Americans and 3.5 million people worldwide came into existence and has charged the CIA and other agencies with doing more to find out.
Hotez, however, said intelligence-gathering alone wasn’t enough.
“I’m personally of the opinion we’ve pushed intelligence as far as we can. What we need to do is an outbreak investigation,” he said, noting that ideally this would be a six- to 12-month operation in Wuhan, in Hubei province, with scientists collecting extensive samples and other forensic evidence.
Initially raised as a possibility by President Donald Trump and some Republicans on Capitol Hill but dismissed by Democrats and many experts, the lab leak theory has gained currency in recent weeks. Many experts cite a World Health Organization report from earlier this year mostly dismissing the possibility as co-authored by Chinese scientists and unconvincing.
The Wall Street Journal, meanwhile, reported last week that a previously undisclosed U.S. intelligence report had found that three scientists from the lab were hospitalized with symptoms consistent with covid-19 as early as November 2019, before the virus began spreading in China.
Both Democrats and Republicans on Capitol Hill have been sounding the call for a deeper inquiry.
“The American people deserve to know about the origins of covid-19,” Sen. Josh Hawley (R-Mo.) said on the Senate floor last week before the passage of a bill requiring the declassification of certain virus information. “We have to have answers to these questions,” said Sen. Tim Kaine (D-Va.), who is on the Senate Committee on Health, Education, Labor and Pensions and endured harsh effects of a coronavirus infection.
There may be growing financial pressure, as well. Rep. Michael McCaul (R-Tex.) on Sunday called for U.S. economic retribution if China doesn’t cooperate.
“My response to this whole thing is supply chain. We need to pull our supply chain out of the region,” McCaul said, citing various industries including medical supplies and semiconductor chips.
Appearing on CNN’s “State of the Union,” McCaul, the ranking Republican on the House Foreign Affairs Committee, said, “If we can pull these chains out of China, it will hurt them economically … and that would be very punitive.” He called Biden’s review “long overdue.”
Experts such as Hotez say it would be extremely difficult to get facts about the virus’s origins without Chinese cooperation.
Some experts say they still think it is unlikely that the virus that causes covid-19 could have come from a lab. But others have noted both the presence of the advanced lab in Wuhan and the lack of horseshoe bats in the city as factors for such a leak.
Former Food and Drug Administration chief Scott Gottlieb said Sunday that the lack of Chinese cooperation provided its own form of circumstantial evidence.
“China could provide evidence that would be exculpatory here,” he said on CBS News’s “Face the Nation,” noting blood samples from lab workers and source strains of the virus. “They have refused to do that.”
Gottlieb said that knowing conclusively whether the virus came from a lab would help inform future security decisions at such facilities worldwide. “It’s important to understand what the possibility is that this came out of lab so we can focus more international attention on trying to get better inventories around these labs, what they’re doing, better security, make sure they’re properly built,” he said.
The virus inquiry has been delicate for the Biden administration, which needs to balance a desire for scientific truth with concerns about stoking violence against Asian Americans, which has registered an alarming rise since the pandemic began.
The White House also must head off geopolitical tensions. China has been pushing back against the growing U.S. call for more transparency.
“The U.S. doesn’t care about facts or truth at all, neither is it interested in a serious scientific study on the origins,” Chinese Foreign Ministry spokesman Zhao Lijian said last week, referencing Fort Detrick, a U.S. Army research laboratory in Maryland. Chinese state media have suggested without evidence that Fort Detrick could be the source of the outbreak. “Its only aim is to use the pandemic for stigmatization and political manipulation to shift the blame.”
