Newshub18 :Wuhan’s Seafood Market Source of Covid: Research.
Two studies aimed at identifying the origin of the coronavirus (Covid-19) that has brought the world to a standstill have come to the same conclusion. It indicated that the deadly virus had spread from the Huanan seafood market in Wuhan, China. News from Sinn.
Last June, the World Health Organization (WHO) advised scientists to continue researching possible sources of the Covid-19 pandemic, including spread from laboratories. According to the published study, the Huanan seafood market in Wuhan, China is the most likely source of the coronavirus. The study was initially published online last February. Peer review is then completed. The study was published in the journal Science on Tuesday.
Researchers use mapping tools and social media reports in a study on spatial and environmental analysis. They say that although the ‘exact cause is unclear’, the virus was likely present in live animals sold on the market in late 2019These animals were housed side by side and easily spread germs from one to another. However, the research has not confirmed which animal may have become illThe researchers confirmed that the market vendors who sold live animals or people who went there to shop were initially infected with Covid-19. According to the study, ‘All the eight people diagnosed with Covid-19 before December 20 (2019) Was on the west side of that market. Mammals were sold there. Humans were exposed to five stalls selling live or recently slaughtered animals”The mapping of specific areas is very, very precise,” study co-author Christine Andersen, a professor of immunology and microbiology at Scripps Research, said Tuesday.

Another co-author, Michael Orobe, head of the Department of Ecology and Evolutionary Biology at the University of Arizona, said the ‘different’ pattern that emerged when mapping the locations of identified patients was very clear.
The researchers found that some of those infected initially had no connection to the market. Orobe said that these people lived or worked near the market.
Michael Orobe also said, ‘This is an indication that the virus is starting to spread among those working in that market. But then when the vendors went to local shops, the people working in those shops were also infected.
Then it started spreading among the local residents around.Another study aimed to ascertain when the virus first passed from animals to humans. The study suggests that the origin of the coronavirus likely came from two separate structures. Scientists named them ‘A’ and ‘B’.
According to researchers, the first animal-to-human transmission probably occurred sometime around November 18, 2019. It came from ‘B’. ‘B’ is found among people who had direct contact with the Huanan market.
The authors of the study believe that A can be transmitted from an animal to a human within a few weeks or even days after being infected with B. Finding ‘A’ in the sample of those who lived or stayed near that market.
The study said, ‘These results indicate that there is little risk of SARS-CoV-2 spreading widely in humans before November 2019. The results also reveal a narrow link between when the virus entered the human body and the first patient identifications. Like other coronaviruses, Sars-Cov-2 is likely caused by multiple “zoonotic events.”
As defined by the US Centers for Disease Control and Prevention (CDC), the disease is caused by a pathogen that spreads between animals and humans.
At the end of 2019, the first corona patient was detected in the Chinese city of Wuhan. Later it became an epidemic and spread all over the world. But what was the source of the virus, there is no definite answer yet.
Debate started over whether the corona came from animals to humans or spread from an accident in a laboratory in Wuhan. Although China has denied the spread of corona from the laboratory from the beginning.
