Proof of origins of the COVID-19 outbreak denies the laboratory leak theory

New research on the origins of the COVID-19 outbreak bring another nail into the coffin of laboratory leak theory. This theory claims that the virus was created or studied either in a laboratory in Wuhan, China, and then either accidentally escaped or was deliberately released.

The new study shows that the path of virus in China to Wuhan that resembles the former Sars epidemic in 2002 in terms of time, distance and route report In the magazine cell. The proof of its origins and travel route essentially denies that the virus in Wuhan appeared out of nowhere.

“The various iterations of laboratory liquid theory assume that the appearance of COVID-19 gives something different and inexplicable compared to the Emergence Sars,” says Joel Wertheim, professor at the Medical School of Medicine at the University of California, and an author of the newspaper. “There is nothing unique about how far Sars-Cov-2 had to appear in Wuhan. The Sars virus basically fulfilled the same task about the zoonotic origin. Therefore, no” laboratory leak “has to be called up to explain the geography of the SARS-COV-2 development.”

Outbreak of Covid-19

Several earlier studies have contested the “laboratory leak theory” with various methods. A 2022 PapeR genetically connected the earliest known human cases with a certain section of the Huanan sea fruits -wholesale market with many wild animals and in which the virus was also found.

Another showed that two different lines of the virus existed before another variant infected people. A third Early versions of the virus with several animals tied on the Wuhan market.

Origin of the virus

The new study shows the origin of the virus essentially a few years before infecting people in West China or Nordlaos. They found that the 1,500 miles between these points and Wuhan were probably too far to make it possible to boost the Horseshoe bat within this time according to its normal method.

Therefore, the virus most likely spread about a faster method, most likely about animal trade with wild animals -just like the virus from 2002. In fact, the Sars virus or the way they traveled has nothing special to Sars virus and finally found their way to man, say the researchers.

“We see this pattern repeatedly: people in contact with animals and the pathogens circulating among them, which leads to spillovers and sometimes devastating human diseases,” says Jonathan Pekar, UCSD researcher.

Persecution of Covid-19 ancestors

Some Covid 19 secrets remain. Researchers are still trying to track down their ancestors (Wertheimer says that scientists come together – maybe about two years away). And you still have not solved a key element in the entry of the virus.

“We still haven't nailed the identity of the hypothetical intermediate taverns that have closed the gap between bats and humans,” says Wertheim. “We have candidates. But unfortunately we may never know.”
