SARS-CoV-2 is not a human virus and it is likely that the virus was not born in a place where the first Corona virus was infected, a prominent virologist said, suggesting that the sources were mostly southwest. Looking for Origin in Asia?
At a public forum in Tianjin, ian-nun, Wang Lanfa, a virologist at Duke-NUS Medical School in Singapore, told a video conference that he believed the virus was not human, before W.A. WHO’s experts arrived earlier this year. And called the “lab leak” theory extremely impossible.
Wang is a renowned international virologist who succeeded in formulating the Hendra virus in 1993 and joined the WHO’s expert team in 2003 to investigate the origin of SARS. Wang Shi is also closely related to Zhengli from the Wuhan Institute of Virology, with which he authored several papers, including one in science in 2005 that identified the horse’s bat-like substance as a starch-like corona virus.
Based on previous experience, Wang rapidly referred to bats as the origin of the coronary virus that caused COVID-19. He said the Prime Corona virus came from the bats. Yet, before the Wuhan epidemic, there must be a “progenitor virus” that shares over 99.9% of its genetic profile with SARS-CoV-2. However, the scientific world is still debating about the “progenitor virus”.
Wang cited an earlier paper posted on Research Square last month that showed that scientists have found three viruses in bats in Laos that are 95% identical to each other in SARS-CoV-2.
Last year, researchers described a relative U-close relative of SARS-CoV-2 called RaTG13, which was found in Chagadatan in Greece. This is 96.1% of the common SARS-CoV-2 and virus N virus shared 40 to 70 years ago.
Most importantly, coronaviruses found in bats shared in Laos with SARS-CoV-2. Contains viruses that are receptor binding domains that are almost identical to the current virus caused by COVID-19.
“When the SARS-CoV-2 was first designed to be enced, the receptor binding domain didn’t really look anything like what we had before,” said Edward Holmes, a virologist at the University of Sydney, Australia. That’s why some people guessed that the virus had been put in a laboratory. But the Laos coronavirus confirms that these components of SARS-CoV-2 are present in nature, Holmes mentioned.
Wang said that, although it was Wuhan who experienced the first outbreak of SARS-CoV-2, the virus was most likely not from there. He cited the example of the HIV virus, which was first detected in New York and California, but was later discovered in Africa. Therefore, it is very likely that SARS-CoV-2 came from a distance.
A recent study was published by Wu Cheng, Chinese Academy of Medical Sciences and fellow Yin fellow scientists at the P-based Institute of Pathogen Biology and fellow Yin fellow scientists who collected 703 samples of pharyngeal and anal swabs from 13,064 bats. C 2016 on China between 2016 and 2016. 2021. However, they did not find SARS-CoV-2 in any of the samples, indicating that the virus would not be widely available in bats in China.
Wang explained that the Chinese province borders Greece with Myanmar, Laos, Vietnam, Malaysia and Sin South and Asian R Asian countries with the most populations today. However. Inadequate research resources have been allocated for this area.
“If given the chance, scientists can find many viruses, such as SARS-CoV-2,” Wang said, noting that if he was given $ 100 million to look at the origin of the corona virus, he would look at 99 percent of the research. ۾ Puts in Southeast Asia.
During the speech, Wang also warned for the coming Corona virus outbreak. “Corona virus is very dangerous to deal with bats, SARS-CoV-3 is doomed to come, just not sure when,” said the virologist, noting that the most possible place for SARS-CoV-3 is JS. The southwest is Asia.
