More than a year after the coronavirus pandemic began, the World Health Organization released a report on Tuesday about how the virus spreads for the first time in humans – but it is already raising more questions than answers, including which health bodies Includes its own leader.
Report, Prepared by a 34-member team of Chinese scientists and international experts who led a mission in Wuhan, China, to investigate a series of politically controversial questions that may also include the virus Accidentally emerged From a Chinese laboratory.
Some members of the expert team have raised concerns about China Refuse to share raw data Regarding early Kovid-19 cases. In an unusual move, the Director General of WHO, Drs. Tedros Adenholm Ghebreyus, while speaking about the report on Tuesday, acknowledged those concerns. He said he hoped future studies would include “more topical and broader data sharing”.
Here we know about it Report good.
Experts rejected a laboratory leak theory.
For months, scientists, politicians and others from outside China have promoted the theory that the virus may have emerged after a laboratory accident in China. While many experts are skeptical of this theory, they have urged the WHO team to rigorously investigate the possibility.
The report rubbished the theory of lab leaks, calling it “highly unlikely”. Experts base their conclusions largely on interactions with scientists in Wuhan.
But WHO chief Drs. Tedros made the unexpected move publicly raising doubts, stating that the theory needed further investigation and that he was prepared to deploy more experts to do so.
“I don’t believe this assessment was comprehensive enough,” he said in a briefing for member states as reported on Tuesday, Ready comment Released to the news media. “Further data and studies will be needed to reach a more robust conclusion.”
Experts had said that officials at the Wuhan Institute of Virology, a state-of-the-art laboratory known for their research on baton coronaviruses, assured them that they were not handling any viruses that appeared closely to the coronovirus Give. According to the notes included in the report, the recent epidemic caused. He also said that staff members were trained in security protocols.
The report said that a separate laboratory operated by the Wuhan Center for Disease Control and Prevention moved to a new location nearby in late 2019. Huanan Seafood Wholesale Market In Wuhan, where many early cases of Kovid-19 occurred. The expert team said there is no connection, writing that the lab had not reported “disturbances or incidents caused by the move” and was not researching coronaviruses.
Some critics have suggested that the team faced China’s official position, and it was presumed that they did not adequately investigate the claims of laboratory officials.
Raina McIntire, head of the biosecurity program at the Kirby Institute at the University of New South Wales in Sydney, Australia, said the report rejected the idea of a laboratory leak.
“A laboratory accident is definitely a possibility,” she said.
The role of animal markets is still unclear.
The expert team concluded that coronoviruses emerged in bats before possibly spreading to humans via an intermediate animal. But the team said there was not enough evidence to identify the species or identify animals where the virus had previously leaked from the animals.
At the onset of the epidemic, Chinese authorities suggested that an outbreak of coronovirus may have started in the Huan market. According to the report, more than a year later, the role of animal markets in the epidemic story is still unclear.
The expert team found that many early cases had no apparent connection to the Huan market, which sold Sika deer, badgers, bamboo mice, live crocodiles and other animals, according to the records of the seller cited in the report.
The report noted that in early confirmation cases, about 28 percent were linked to the Huan market and 23 percent to other markets in Wuhan, while 45 percent had no history of market risk.
“So no concrete conclusions have been reached about the role of the Hunan market at the core of the outbreak or how the transition was introduced to the market,” the report said, which could be drawn at this time.
It added that further studies of farms and wild animals are needed in China, and more clues about the role of markets can be revealed.
The success of the investigation will depend on China.
The expert team provides a long list of recommendations for additional research: more testing of wildlife and livestock in China and Southeast Asia, more studies on early cases of Kovid-19, and more tracing of routes from markets to markets in Wuhan.
But it is unclear whether China will cooperate, repeatedly hindering WHO inquiries. Chinese authorities have sought to draw attention elsewhere, suggesting that the virus may have emerged in the United States or other countries.
Experts say delays in interrogation have damaged the ability to prevent other epidemics.
“This delay has clearly compromised the investigative ability to reconstruct the origins of Kovid-19 and identify ways to reduce the risk of such incidents occurring again in the future,” University of Otago public Professor of Health Michael Baker said. In New Zealand.
