Exclusive: The Chinese Scientist Who Sequenced the First COVID-19 Genome Speaks Out About the Controversies Surrounding His Work


Over the previous few years, Professor Zhang Yongzhen has made it his enterprise to sequence hundreds of beforehand unknown viruses. However he knew immediately that this one was significantly nasty. It was about 1:30 p.m. on Jan. three {that a} metallic field arrived on the drab, beige buildings that home the Shanghai Public Well being Medical Middle. Inside was a check tube packed in dry ice that contained swabs from a affected person affected by a peculiar pneumonia sweeping China’s central metropolis of Wuhan. However little did Zhang know that that field would additionally unleash a vicious squall of blame and geopolitical acrimony worthy of Pandora herself. Now, he’s searching for to set the file straight.

Zhang and his workforce set to work, analyzing the samples utilizing the newest high-throughput sequencing expertise for RNA, the viral genetic constructing blocks, which operate much like how DNA works in people. By 2 a.m. on Jan. 5, after toiling by means of two nights straight, that they had mapped the primary full genome of the virus that has now sickened 23 million and killed 810,000 throughout the globe: SARS-CoV-2. “It took us lower than 40 hours, so very, very quick,” Zhang tells TIME in an unique interview. “Then I noticed that this virus is carefully associated to SARS, in all probability 80%. So actually, it was very harmful.”

The occasions that adopted Zhang’s discovery have since change into swathed in controversy. Crises beget scapegoats and the coronavirus isn’t any totally different. The floundering U.S. response to the pandemic has prompted a wave of racially tinged soundbites, akin to “China virus” and “Kung Flu,” as President Donald Trump’s Administration seeks to divert blame onto the nation the place the pathogen was first recognized. “The outbreak of COVID angered many individuals within the Administration and introduced an election situation for President Trump,” Ambassador Jeffrey Bader, previously President Obama’s chief adviser on Asia, stated at a latest assembly of the Overseas Correspondents Membership of China.

Upon first acquiring the genome, Zhang says he instantly referred to as Dr. Zhao Su, head of respiratory drugs at Wuhan Central Hospital, to request the scientific information of the related affected person. “I couldn’t say it was extra harmful than SARS, however I informed him it was actually extra harmful than influenza or Avian flu H5N1,” says Zhang. He then contacted China’s Ministry of Well being and traveled to Wuhan, the place he spoke to prime public well being officers over dinner Jan. 8. “I had two judgements: first that it was a SARS-like virus; second, that the virus transmits by the respiratory tract. And so, I had two recommendations: that we should always take some emergency public measures to guard towards this illness; additionally, clinics ought to develop antiviral therapies.”

Afterward, Zhang returned to Shanghai and ready to journey to Beijing for extra conferences. On the morning of Jan. 11, he was on the runway at Shanghai Hongqiao Airport when he obtained a cellphone name from a colleague, Professor Edward Holmes on the College of Sydney. A couple of minutes later, Zhang was strapped in for takeoff and nonetheless on the cellphone—then Holmes requested permission to launch the genome publicly. “I requested Eddie to present me one minute to suppose,’” Zhang remembers. “Then I stated okay.” For the following two hours, Zhang was cocooned from the world at 35,000 toes, however Holmes’ publish on the web site Virological.org despatched shockwaves by means of the worldwide scientific neighborhood.

By the point Zhang touched down in Beijing, his discovery was headline information. Officers swooped on his laboratory to demand an evidence. “Perhaps they couldn’t perceive how we obtained the genome sequence so quick,” says Zhang. “Perhaps they didn’t absolutely imagine our genome. So, I believe it’s regular for the authorities to verify our lab, our protocols.”

Critics of China’s response have latched onto the Jan. 11 date of publication as proof of a cover-up: why, they ask, didn’t Zhang publish it on Jan. 5, when he first completed the sequencing? Additionally, Zhang’s lab was probed by Chinese language authorities for “rectification,” an obscure time period to suggest some malfeasance. To many observers, it appeared that livid officers scrambling to snuff out proof of the outbreak have been punishing Zhang merely for sharing the SARS-CoV-2 genome—and in the intervening time, slowing down the discharge of this key info.

But Zhang denies stories in Western media that his laboratory suffered any extended closure, and as a substitute says it was working furiously through the early days of the outbreak. “From late January to April, we screened greater than 30,000 viral samples,” says Fan Wu, a researcher who assisted Zhang with the primary SARS-CoV-2 sequencing.

And, the truth is, Zhang insists he first uploaded the genome to the U.S. Nationwide Middle for Biotechnology Info (NCBI) on Jan. 5—an assertion corroborated by the submission date listed on the usgovernment establishment’s Genbank. “Once we posted the genome on Jan. 5, the US actually knew about this virus,” he says. However it will probably take days and even weeks for the NCBI to have a look at a submission, and given the gravity of the state of affairs and buoyed by the urging of colleagues, Zhang selected to expedite its launch to the general public, by publishing it on-line. (Approached by TIME, Holmes deferred to Zhang’s model of occasions.) It’s a call that facilitated the swift growth of testing kits, in addition to the early dialogue of antivirals and doable vaccines.

Zhang, 55, is eager to downplay the bravery of his actions. However the stakes of doing what is correct over what one is informed are rendered far larger in authoritarian methods like China’s. A number of whistleblower medical doctors have been detained early within the pandemic. In line with a Jan. three order seen by revered Beijing-based finance journal Caixin, China’s Nationwide Well being Fee, the nation’s prime well being authority, forbade the publishing of any info concerning the Wuhan illness, whereas labs have been informed to destroy or switch all viral samples to designated testing establishments. Caixin additionally stories that different labs had processed genome sequences earlier than Zhang obtained his pattern. None have been printed.

It’s troublesome to know what conclusions to attract. Dr. Dale Fisher, head of infectious ailments at Singapore’s Nationwide College Hospital, says he doesn’t suppose that any delay by the Chinese language authorities was malicious. “It was extra like acceptable verification,” he says. Fisher traveled to China as a part of a World Well being Group (WHO) delegation in early February and says outbreak settings are at all times complicated and chaotic with individuals uncertain what to imagine. “To truly have the entire genome sequence by early January was excellent in comparison with outbreaks of the previous.”

In fact, Zhang’s fears primarily based on the viral genome have been only one proof strut to tell China’s decision-making course of, alongside public well being information and scientific stories about particular circumstances. Regardless of mounting proof of human-to-human transmission, together with medical doctors falling unwell, it was solely on Jan. 20 that China formally confirmed neighborhood transmission. Two days later, Wuhan’s 11 million residents have been positioned on a bruising lockdown that may final for 76 days. Even whereas the WHO publicly praised China for transparency, inner paperwork seen by the Related Press counsel well being officers have been privately annoyed by the sluggish launch of data. One joint examine by scientists in China, the U.Ok. and U.S. suggests there would have been 95% fewer circumstances in China had lockdown measures been launched three weeks earlier. Two weeks earlier, 86% fewer; one week, 66% fewer.

But there was some historic foundation for skepticism concerning the severity of the rising viral illness. In any case, the final world pandemic—the swine flu outbreak of 2009—was far much less lethal than initially feared, primarily as a result of many older individuals had some immunity to the virus, resulting in criticism that the WHO was overly hasty and even overly dramatic in declaring a pandemic when the virology didn’t warrant it. “In China, despite the fact that we had a really dangerous expertise with SARS and different ailments, at first no one—not even specialists from China’s CDC and the Ministry of Well being—predicted the illness may very well be fairly so dangerous,” says Zhang.

Donald Trump disagrees. He has repeatedly claimed that swifter motion by China might have stopped the pandemic in its tracks. “The virus got here from China,” Trump stated Aug. 10. “It’s China’s fault.” Beijing concedes that errors have been made on the outset, although insists that blame lies solely with bungling native officers (who’ve since been punished for these failures), whereas the central authorities’s response was exemplary. That is, in fact, its personal politically motivated oversimplification. On either side, wild accusations have eclipsed purpose as Sino-U.S. relations spiral to an unprecedented nadir. Whereas U.S. officers have steered that COVD-19 originated in a Wuhan laboratory, their Chinese language counterparts have propagated conspiracy theories that the U.S. army is accountable. “It’s not a great factor for China and the U.S. to be concerned on this battle,” says Zhang. “If we will’t work collectively, we will’t remedy something.”

Some information are simple. The primary U.S. case was confirmed on Jan. 21—a person in his 30s who had simply returned from Wuhan to his hometown in Washington State. Japan confirmed its first coronavirus case someday later, and reported the world’s highest an infection quantity early within the outbreak, earlier than getting a deal with on the state of affairs. At this time, the U.S. has 16,407 circumstances per million inhabitants in contrast with 462 in Japan. The world over, authoritarian and democratic nations have each dealt with the disaster effectively and poorly.

For its half, the worldwide scientific neighborhood has risen to the problem, working throughout nationwide boundaries to advance understanding of the illness, together with priceless collaborations between Chinese language and Western virologists. Beforehand, the perfect described epidemic when it comes to viral genetics was the 2014 West African Ebola outbreak. Then, about 1,600 genomes have been mapped over three years, offering insights into how viruses transfer between places and accumulate genetic variations as they do. However for SARS-CoV-2, following Zhang’s preliminary genome, scientists mapped about 20,000 inside three months. Genomic surveillance permits scientists to hint the pace and character of genetic modifications, with ramifications for an infection charges and the manufacturing of vaccines and antivirals. “Very large-scale genomic screening can consider whether or not any resistance mutations have occurred and, in the event that they do, how these unfold by means of time,” says Oliver Prybus, professor of evolution and infectious illness at Oxford College.

For Zhang, focus should now be on understanding how pathogens and the setting work together. Over the previous century, an inordinate variety of new viral ailments have emerged in China, together with the 1956 Asian Flu, 2002 SARS and 2013 H7N9. Zhang attributes this to China’s various ecology and massive inhabitants. Furthermore, as China’s economic system boomed its individuals have begun touring far and vast searching for work, training and alternatives. In line with the World Financial institution, nearly 200 million individuals moved to city areas in East Asia through the first decade of the 21st century. In China, 61% of the inhabitants lived in city areas in 2020 in contrast with simply 18% in 1978. This brings unknown pathogens and other people with out pure defenses into shut proximity. “Individuals and pathogens should keep in touch [for outbreaks],” says Zhang. “If no contact, no illness.”

As urbanization intensifies, outbreaks of pathogenic ailments will solely change into extra widespread. Mitigation, says Zhang, comes from deeper understanding of viruses, in order that we will precisely map and predict that are more likely to spill over into human populations. Simply as satellites have made forecasting climate patterns unerringly dependable, Zhang believes science holds the important thing to predicting viral outbreaks with related accuracy as with which we now anticipate typhoons and tornadoes. “If we don’t be taught classes from this illness,” says Zhang, “humankind will undergo one other.”
