A new research review of the investigation into the origin of the Corona virus says that Covid-19 started in a market in the Chinese city of Wuhan.
Experts have re-examined research into the outbreak of the virus in the Chinese city of Wuhan, one of which said early cases of the virus were reported from a market in and around Wuhan. Another study used genetic information to determine the timing of outbreaks. A re-examination of both investigations revealed evidence that a seafood and wildlife market in the Chinese city of Wuhan was the epicenter of the outbreak at the time of the outbreak. Experts say evidence indicates that as of late 2019, animals being sold at markets in Wuhan carried the Sars-Cov-2 virus, which was transmitted to humans who worked and shopped there. .

According to the experts, the research review shows that two types (variants) of the virus had infected humans from November to the beginning of December 2019.
This information comes after 2 years of efforts by experts to trace the origin of Corona, before experts were unable to understand if the animal market in Wuhan was the center of the Corona epidemic. If so, why were there only 50 patients who had a direct link to the market among the hundreds of patients affected by Corona in Wuhan?
Professor David Robertson of the University of Glasgow, involved in the research review, said that according to what we now know about Corona, it happened in exactly the same way that only 50 of the early Corona patients in Wuhan had no direct link to the market. But the rest of the people were also outside, so the virus kept infecting people by passing from one to another, so they had no direct link to the market. The study mapping the Covid-19 cases has also revealed that the majority of the early patients who had no direct contact with the market were those who lived in the vicinity of the market. .
