Global Quest to Trace the Origin of COVID-19
There are still no serious doubts in the world about the origin of the Covid 19 virus. More recently, a group of 18 scientists led by Jesse Bloom, who is studying the origin of the covid 19 virus at the Fred Hutchinson Cancer Research Center in the United States, wrote a letter asking to find out if the virus was an accidental leak by mistake or not. It is of natural origin. At India Today, we decided to reach out to these groups of scientists and researchers to learn more about the possibility that the SARSCoV2 virus originated from an accidental laboratory leak. The wet market theory was soon found to be insufficient, as epidemiologists found non-wet market cases even in the early stages of transmission. Starting in Wuhan, the site where the first origin of COVID 19 was discovered is also where the Wuhan case is located.
Institute of Virology, many experts, have expressed concern about the possible leak of the laboratory hypothesis. Another argument by Andersen in favour of the theory of natural origin is that the mutant protein of the SARSCoV2 virus binds well to the human ACE2 receptor, but not in the same way as in best-fit calculations. No similar identification for SARSCoV2 was found even 16 months after the outbreak. They created a new virus by taking the basis of the SARS1 virus and replacing its mutant protein with the protein from the bat virus. This produced virus can infect human respiratory cells when tested in a culture of these cells in the laboratory.
It is noteworthy and important to remember that a few months after the Covid outbreak, Peter Dasha led a team of scientists who said the SARSCoV2 virus was not the result of a laboratory leak. The experiments that he conducted in Wuhan Institute of Virology. LOCATION OF ORIGIN: Samples of the virus similar to SARSCoV2 were found in a bat cave in Yunnan, 1,500 km from Wuhan. Dr Alina Chan said, “For me, the most important thing is how the virus, whose closest relative lives in southern China, got to Wuhan, central China, thousands of miles away, leaving no trace of its first spread. From people and from person to person before getting to Wuhan. "
EVOLUTION OF THE VIRUS: Unlike SARS1, which has recorded successive changes in the apical protein during its stepwise evolution into a dangerous pathogen, the SARSCoV2 virus remained practically unchanged until recently. Mutations. Alina Chan added: "By the time SARSCoV2 was first detected at the end of 2019, it was pre-adapted for human transmission to the same extent as the late SARSCoV2 epidemic." Experts also note that the strains first identified in Wuhan show limited genetic diversity, suggesting that the virus may have come from a single source.
Now the obvious question is: What did the CDC and HIV do with all this information and then sampling bats from these regions? Why are these incidents not recorded, and their truth not revealed to the outside world? Did China know how to deal with the pandemic between the April 2012 miner incident and the SARSCoV2 outbreak, and hasn't it shared it with the rest of the world? Or did one of your experiments lead to a laboratory accident that led to the release of HIV? Why is the Dr Shi 2013FY113500 pathogen database no longer available? At the same time, the Wuhan Municipal Center for Disease Control and Prevention held an emergency tender for the purchase of virus detection kits, including 40,500 PCR kits.
In a nutshell, Alina Chan says, “We know that HIV has sampled tens of thousands of animals and even thousands of people living near these SARS hotspots in southern China. It is perfectly justified that SARSCoV2. To Wuhan for this research activity. That's what happened, we need to convene an international forum of non-scientific stakeholders to look at the types of pathogen research that are being done around the world and decide how to act globally to prevent a new pandemic from recurring. ”
Dr Sonali said the likelihood that the SARSCoV virus was the result of another pandemic virus modified in the laboratory is slightly higher. “Key features, receptor-binding domain and Turin cleavage site are two features that can provide markers for modification in the laboratory. The virus, when detected and infected, has adapted to humans and therefore the possibility that the virus is either laboratory or genetic can be altered using the spine. It is Wuhan is home to one of the two most famous laboratories doing this job.
Working on SARS and SARS-like Corona viruses, HIV. An outbreak of the disease has begun in Wuhan. Two other institutes, Wuhan CDC and Wuhan University, are investigating the coronavirus. In addition, there are other laboratories in China.
