Newest Coronavirus Information
FRIDAY, Nov. 19, 2021 (HealthDay Information)
The primary identified particular person with COVID-19 was a vendor in a big seafood market in Wuhan, China, claims an American scientist whose findings problem the World Well being Group’s conclusion that the primary affected person was an accountant who lived miles from the market.
Michael Worobey, a College of Arizona knowledgeable in tracing the evolution of viruses, examined quite a few sources of knowledge and found discrepancies within the WHO’s timeline for the beginning of the pandemic.
The seller’s hyperlinks to the Huanan Seafood Wholesale Market and a brand new evaluation of the earliest hospitalized sufferers’ connections to the market strongly recommend that is the place the pandemic started, based on Worobey, whose findings have been printed Thursday within the journal Science.
“On this metropolis of 11 million folks, half of the early instances are linked to a spot that is the scale of a soccer discipline,” Worobey informed The New York Occasions. “It turns into very troublesome to elucidate that sample if the outbreak did not begin on the market.”
Whereas quite a few consultants agree with Worobey’s conclusion, some say he would not present definitive proof of how the pandemic started.
“I do not disagree with the evaluation,” Jesse Bloom, a virologist on the Fred Hutchinson Cancer Analysis Heart in Seattle, informed the Occasions. “However I do not agree that any of the information are robust sufficient or full sufficient to say something very confidently, aside from that the Huanan Seafood Market was clearly a super-spreading occasion.”
Research of the virus’ genome — together with one performed by Worobey himself — recommend that the primary an infection occurred in about mid-November 2019, weeks earlier than the market vendor received sick, the Occasions reported.
The virus possible contaminated a “affected person zero” someday earlier than the seller turned sick after which began to unfold extensively on the market, some have recommended.
Whereas Worobey’s paper will rekindle debate over whether or not the pandemic resulted from animal-to-human switch, it possible will not settle the problem.
“He has completed a superb job of reconstructing what he can from the out there knowledge, and it is as affordable a speculation as any,” Dr. W. Ian Lipkin, a virologist on the Mailman College of Public Well being at Columbia College, informed the Occasions. “However I do not suppose we’re ever going to know what is going on on, as a result of it is two years in the past and it is nonetheless murky.”
