Corona is not gone yet, nor do we know the exact reason behind the birth of Corona. Everyone says that China is the creator of Corona. But where did Koro come from, who made it and why it was made. These questions are still as unresolved as the sure treatment of corona is not known. Corona gave the biggest tragedy of this era in the world. Right now the threat of a third wave is hovering over its head. Even today, about 30 thousand cases are being reported daily in India. But now we tell you the research that has come out about Corona. Seafood market of Wuhan city of China…Whenever the name of Corona comes, we get angry at Wuhan city of China. First of all, many initial cases of Covid-19 were reported in this place. But despite the passage of 21 months, it is still not known how the very dangerous corona virus finally reached this market. Initially, scientists said that this virus reached humans naturally through an animal. Some even said that it was leaked from a lab in Wuhan, a few miles away from this seafood market, where many types of viruses are tested. But this claim was dismissed as a rumour. China is so shameless that it still does not believe that we have given the pain of the virus to the world.
Where did it come from… why is it difficult?
Every time a major disease shows its vicious form, that is, it becomes formidable by the rule that destroys everything, then the first question of scientists and people is where did it come from. To prevent future outbreaks and predict epidemics like COVID-19, researchers need to trace the origins of the viruses that cause these diseases. This is no easy task. The origin of HIV is still unclear, 20 years after its worldwide spread. Scientists still don’t know the origins of Ebola, even though it has caused periodic epidemics since the 1970s. Bats were an obvious first place when it comes to Corona. They are known for several coronaviruses and are likely sources of other animal-borne diseases such as SARS and MERS. Scientists from the study found that BatCov RATG13 is closest to SARS-CoV-2, the virus that causes COVID-19. is the form. The virus is part of a collection of bat coronaviruses discovered by virologists at the Wuhan Virology Institute in 2011 and 2012. After the SARS-CoV-1 pandemic in 2003, virologists were looking for SARS-related coronaviruses in bats. They collected bat stool samples and throat swabs at a site in Yunnan province, about 932 miles from the institute’s laboratory in Wuhan. They brought the samples back to Buhan’s laboratory for further study. To test whether bat coronavirus could spread to people, the researchers infected monkey kidney cells from Yunnan samples and cells derived from human tumors. They found that many of the viruses in the samples collected could increase their numbers in human cells, meaning they could potentially be transmitted directly from bats to humans without any intermediate hosts. However, bats and people do not often come into direct contact, so there is still great potential for an intermediate host.
WHO report after China tour
A team of WHO went to China to investigate it. In the report of the investigation team, some important things were told about the corona epidemic. WHO Director-General Dr Tedros Adhanom Ghebreyesus said, “This report is a very good beginning but it is not the end.” We are yet to know the source of the virus. This document has been prepared after the investigation of a group of 17 experts from China and 17 international experts. The investigation team reached China in late January this year where they visited hospitals, markets and laboratories for 14 days. They gathered official data, reviewed studies from other countries, and analyzed samples taken from farms supplying markets in South China. However, the investigation was carried out under the strict control of the local authority, who initially opposed it. The 120-page report outlines four possibilities regarding the origin of the virus and its spread to humans. Based on the evidence found here, experts have drawn conclusions. According to the report, there is solid evidence that many corona viruses that reached humans originated from animals. According to the document, the animal from which this virus has reached in humans can be bats. Bats are among the animals that contain many viruses that can spread to humans. Another possibility says that the animal that got the corona for the first time may have infected another animal before humans. Humans may have been infected again by that other infected animal. The third is the possibility of reaching humans through food items. This hypothesis says that the Covid-19 virus has reached humans through food items or containers containing them. This includes frozen foods that are commonly sold in markets in Wuhan. There is evidence for the possibility that SARS COVID-2 can persist in infected frozen products. In recent times, this point has been repeatedly emphasized in the Chinese state media. They point towards the goods coming from abroad. The fourth possibility has been raised that due to an accident in the laboratory, the virus spread among the workers there. The document clarifies that they did not analyze the possibility that someone intentionally spread the virus. He also did not inquire about whether the virus was produced in the laboratory, as this possibility has already been ruled out by other scientists based on analysis of the virus genome.
Whose role in the origin of the pandemic?
The initial cases of COVID-19 were linked to the Hunan market located in the Chinese city of Wuhan. Since the beginning of the epidemic, Wuhan was seen as the source of the corona virus. But, the investigation said that there is no evidence to reach this conclusion. that this place had any role in the origin of the epidemic. The document states that although the initial cases are related to the market in Hunan, there have been similar cases in other markets. Many other matters are not even related to the markets. The team confirmed that there was widespread SARS-Covid-2 infection in the Hunan market in Wuhan but its source could not be traced. This, the report says, suggests that the Hunan market is not the true source of the epidemic. Research also suggests that the virus may have arrived in the Wuhan market from farms from where the market is supplied and there is a large amount of SARS-Covid-2 found in bats. However, the document also states that it Shows no link but creates another possibility to investigate. When the first outbreaks of the coronavirus were detected, the Hunan market was attracting animal products from 20 countries, including some that reported cases of SARS-Covid-2 at the end of 2019. Peter Daszak, one of the WHO representatives in this research, says that farm animals in Southeast Asia are the most likely source of epidemic onset.
