Corona Virus Trusted from Laboratory Leaks

The exact origin of the corona virus is still unclear. But some people said the virus came from a laboratory leak in Wuhan City. Is it true?

KThe controversy about the origin of SARS-CoV-2 as the cause of Covid-19 disease continues. The most recent comes from the former Director of the United States (US) Center for Disease Control and Prevention, Robert Redfield. He said the corona virus came from a laboratory in Wuhan.

In an interview with CNN On Friday (26/3) he believed that the SARS-CoV-2 virus originated from the Wuhan laboratory without mentioning a specific institution. He admitted that he had no evidence. “I’m allowed to have an opinion now,” he said.

“I still think that most likely the cause of this pathogen in Wuhan came from the laboratory. Other people don’t believe it, it’s okay. Science will eventually find out,” he said.

So far, the origins of SARS-CoV-2, the virus that causes Covid-19, have been hotly debated. Some experts say the public may never know exactly where the virus originated. But the idea at the start of the virus pandemic is thought to have originated with the Wuhan Institute of Virology (WIV).

Redfield’s statement differs from the findings of the World Health Organization (WHO). Through a disease ecologist from the EcoHealth Alliance as well as a member of the WHO delegation to China, Peter Daszak, unofficially leaked information related to the results of the WHO investigation in Wuhan.

According to him, the WHO team found new evidence of the corona virus coming from wildlife farms. Ranchers supply the animal to traders at the Huanan seafood wholesale market in Wuhan City. This is in line with the Chinese government’s suspicion, which views wildlife farming as the most likely route.

The WHO investigation is in line with the statements of a number of scientists. They suspected that the most likely explanation, the virus emerged naturally. He passed from bats to other animals, then to humans.

Do not believe

However, Redfield said he did not believe the bat theory put forward by a number of scientists and the WHO. “Typically, when pathogens move from zoonoses to humans, it takes a while to figure out how to become more efficient at human-to-human transmission,” said Redfield. “I don’t think this makes sense biologically,” he added.

Although he believes the virus originated in a laboratory, Redfield did not call SARS-CoV-2 an engineered virus. “Yeah, let’s just say I have a coronavirus I’m working on. Most of us in the lab, trying to grow the virus. We’re trying to help make it grow better and better and better so we can experiment,” said Redfield.

Redfield’s view is supported by several experts. They noted that the SARS-CoV-2 genome is genetically different from other coronaviruses that are being studied in the Wuhan laboratory. The changes that occurred made it impossible as a result of the laboratory ‘breakout’.

“The SARS-CoV-2 virus has several key differences in specific genes relative to previously identified coronaviruses that the laboratory will work on,” said University of Michigan Medical School professor of microbiology and immunology and infectious diseases, Dr. Adam Lauring.

Responding to Redfield’s statement, Director of the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Anthony Fauci, said, “Obviously, there are a number of theories. Dr. Redfield mentioned that he was giving an opinion on the possibilities. But then again, there is an alternative that most people hold,” Fauci said.
