Scientists discover the origin of David-19: He didn't leave the lab.

Two recently published studies have completely different approaches, but they come to the same conclusion: The food market of living things in Wuhan, China, is most likely to be the artiferous epidex.

In one of the studies, scientists from around the world used maps and social media reports to do a deeper analysis. They suggest that although the <x0 circumstances remain unclear”, the virus was probably present in living animals sold on the market at the end of 2019.

Animals were kept close together and may easily have exchanged germs. However, the study does not determine which animals may have been infected. Scholars determined that the earliest cases of Covid-19 were registered in the market between vendors selling these living animals or the people shopping there. They believe that there were two separate viruses that circulated among animals that later spread to humans.

The eight cases of COVID-19 that were discovered before December 20th were on the western side of the market, which included the sale of mammals”, according to the study.

Researchers studied the first market - related cases, and those people lived or worked near the market.

This is an indication that the virus started spreading to people who worked in the market, and then it started spreading to the local community after the vendors went to local stores, and infected the people who worked in those stores,” said Woblay.

The next study seems to determine when the virus began spreading from animal to human. The earliest version of the choreography may have appeared in various forms that scientists call A and B.

Researchers suggest that the first transmission from animal to human life may have occurred about November 18, 2019, by type B. They found type B only in people who had a direct connection to the market in Wuhan.

The authors believe that the virus passed on to humans from an animal within weeks.

These findings show that it is unlikely that SARS-CoV-2 would circulate widely among people before November 2019 and determine the narrow window between the time the SARS-CoV-2 first spread to people and when the first cases of COVID-19 were reported. “, says the study.

As with other coronarys, the spread of SARS-CoV-2 is likely to be of animals. ”

Andersen said that studies do not ultimately dismiss the theory of laboratory flow, but are extremely convincing, so that he changed his mind about the origin of the virus. To reduce the chances of future pandemics, researchers hope that they can determine exactly which animal may have been infected first and how, reports abcnews.al.

The components of a zoonotic virus with pandemic potential are still hidden in nature,” said Wertheim. He believes that the world should do much better work by monitoring and monitoring animals and other possible threats to human health.

Andersen said that although we cannot prevent explosions, co-operation among world scientists can be the key to the difference between a minor illness and what kills millions.
