Reported from BBCSome scientists believe that the Huanan Market is the epicenter of the Covid-19 outbreak. They have strong evidence through two studies that have been reviewed by various researchers.

One study showed that the initial cluster cases occurred around the market.
Meanwhile, another study uses genetic information to track the timeline of outbreaks. The study said there were two variants of the virus that were transmitted to humans in November or early December 2019.
When the two studies were combined, the researchers found evidence to build a picture that the Sars-Cov-2 virus, which was present in a number of live mammals sold at the Huanan Market, in late 2019. The virus was then transmitted to people who work or shop there. in two separate transmission events.
Virologist Professor David Robertson of the University of Glasgow was one of the researchers involved in the study.
“I hope these studies will correct the false record that the virus came from a laboratory,” he said.
He said that they were really confused at that time. Most cases are not directly related to the market.
“But now that we know about the virus, it turned out to be as we thought. Since many people are only mildly ill, they will travel around the community transmitting the virus to other people and severe cases will be difficult to relate to each other,” he added.
The Covid-19 mapping research found that most of the initial patients who had nothing to do with the market, aka not working or shopping there, actually lived near the market.
This reinforces the notion of the market as the epicenter of the epidemic, said Professor Michael Worobey, lead author of the study and a biologist at the University of Arizona. According to him, the sellers in the market are the first to be infected and then create a chain of transmission among community members in the surrounding area.
“In a city that covers more than 7,700 square kilometers, the area most likely to contain the home of a person with the world’s first Covid-19 case is the area of several city blocks, the center of which is Huanan Market,” Worobey said.
This study also focuses on the market itself. Scientists created maps of fluid samples from sewers and market stalls that tested positive for the virus.
Most of the positive samples were clustered around the southwest side of the market. That’s where they reported the sale of animal species such as raccoons.
“So we confirmed the animals that we now know are vulnerable [pada Sars-Cov-2, virus yang menyebabkan Covid-19] sold there in 2019,” said Prof Worobey.
