According to Business Insider, genetic research has revealed that the virus originated from Chinese bats and was later found in the human body as a vector. There is no consensus on where and how this story began.
Initially, officials from the Chinese city of Uhan announced that the first cases of the new coronavirus originated from the local seafood market in Wuhan. After research into live products sold there, representatives from the Chinese Center for Disease Control and Prevention announced last week that they were rejecting a version of the market as the source of the primary outbreak of the virus.
Gao Fu, head of China’s Centers for Disease Control and Prevention, said in a Wall Street Journal: “It is now clear that the market is just one of the victims.”
Examination of samples of animals marketed to detect coronaviruses has shown that they are all negative, leading to the conclusion that they cannot infect buyers.
Wuhan Market
Wuhan officials first notified the World Health Organization of an unknown pneumonia-like illness, later called the new coronavirus, on December 31.
Most of the first 41 cases refer precisely to said market, which closed on January 1.
Given that the SARS outbreak began in 2002 and 2003 at a similar location in Guangonde, China, experts concluded that the Wuhan live market is the likely source of the virus (the SARS coronavirus leaped from the bat into the civet and from this animal. to the human body).
Interestingly, no animal has been diagnosed with the new coronavirus on the market, says Colin Carlson, a geologist at Georgetown University. If they were not infected, they could not become vectors of the virus and cause an outbreak of the virus.
There is a growing body of evidence to support the Chinese Center for Disease Control and Prevention’s conclusion that the source of the virus has nothing to do with Wuhan’s live market.
The Uhane virus appears to have been circulating before 41 cases were reported: Data from a study published in January shows that the first person to be diagnosed with the new coronavirus was infected on December 1 and had symptoms on December 8. The researchers also found that 13 of 41 cases had nothing to do with the Wuhan Live Market.
The results of a survey conducted in April suggest that the virus had already established itself and was spreading in the Wuhan community in early January.
The identity of the so-called zero patient has not been officially confirmed, but it could be a 55-year-old resident of Hubei province, China, who became infected on November 17, the South China Morning Post wrote in state documents.
According to Carlson, Live Science, the Wuhan Live Market may have been the site of an early and ultrafast spread of the virus, for example, when an ill person infects an unusually large number of people.
Other cases that have contributed to the spread of the virus worldwide have also contributed to the formation of new outbreaks of coronavirus. In South Korea, for example, in Daegu, a virus carrier who arrived at a prayer house infected at least 43 people.
These cases are not necessarily related to the fact that the person in question is more contagious or has released more virus particles into the environment. Chances are, a person carrying the virus is simply in a space where the virus is conducive to spreading, known to many people. A market where buyers interact with each other and with sellers is one of those places that is highly conducive to the spread of the virus.
Issues related to the origins of the pandemic are intertwined with a wide variety of theories. According to one, the new coronavirus may have been mistakenly leaked from a local laboratory, the Wuhan Institute of Virology, where researchers are studying coronaviruses.
Scientists in both China and the United States say they have no evidence to support such a theory. The representatives of the special security laboratory say that they do not have records of the new coronavirus and ensure that they always meet extremely strict security requirements.
Wang Yanyi, head of the Wuhan Virology Institute, told Chinese state television that the new coronavirus is genetically different from other live viruses studied by the institute’s researchers.
Previously, Shi Zhengli, a researcher at the Wuhan Institute of Virology who studies coronaviruses found in Chinese bats, told Scientific American comparing the genome of the new coronavirus with genetic information from other bat coronaviruses collected by her team. No matches found.
“Then I really felt relieved. I haven’t slept many nights before, “says Shi Zhengli.
