The newly released US intelligence report is a novel Coronavirus, SARS-CoV-2, escaped from the laboratory.
by The Wall Street JournalThe report states that three employees of the Wuhan Institute of Virginology sought hospital treatment in November 2019, when SARS-CoV-2 is believed to have begun to spread in Chinese cities. The institute deals with coronaviruses found in animal populations.
However, it is unclear how ill the researchers were or what their symptoms were. According to The Wall Street Journal, China’s healthcare system typically seeks introductory care directly from hospitals rather than outpatient clinics, as to whether employees received inpatient care or were considered outpatients. There is no information.
New information may add pressure to further investigation into the origin of the new coronavirus.Previous studies on viral genetics show No signs of human tampering: This virus is similar to the coronavirus, which is known to circulate in bats and pangolins, but has a mutation in the virus’s speplomer that makes it easier for the virus to invade human cells, from person to person. Allows diffusion to. However, this mutation does not predict that computer simulations will make the virus more contagious. Instead, this genetic fingerprint makes the virus a lucky break, the most likely reason for a pandemic. Random mutations appear to have encountered a sequence that allows the virus to take off on a new host in the classic case of natural selection.Journal March 2020 Treatise Nature medicine..
“This analysis of coronavirus genomic sequences from patients and various animals Virus Adam Rolling, an associate professor of microbiology, immunology, and infectious diseases at the University of Michigan School of Medicine, who was not involved in the study, said. Told Live Science in April 2020..
As the rise of the new SARS-CoV-2 variant shows, The virus mutates regularly, And some of those mutations are associated with changes in how effectively it is transmitted.
The first reported outbreak of the virus occurred at the Huanan Wholesale Seafood Market in Wuhan. Initially, live animals were bred and sold, and some speculated that the virus had leapt from animals to humans on the market.But it soon became clear that the wet market might not have been. The original site of that leap: There was an early case of COVID-19 in the city Not related to shoppers in that market, And there are no SARS-CoV-2 sequences found in animals from the market.Instead, the market seems to have been just a site First recorded Superspreader event..The· World Health Organization (WHO) said The most likely origin of the virus was to spread from bats to other unknown animals and from there to humans.
The origin of the laboratory?
The discovery that the SARS-CoV-2 genome is unlikely to be genetically engineered does not rule out the hypothesis that the virus has escaped from the laboratory. It is possible that it was the naturally occurring virus that was being studied there that inadvertently infected humans. Chinese officials and researchers at the Wuhan facility have denied that the virus was present in the lab. The list of lab-studied viruses released by the institution does not show a close cousin to SARS-CoV-2.
The Wuhan Institute of Vase is the first biosafety level 4 facility in China. That is, it is designed for the study of potentially dangerous pathogens, and researchers are taking precautions against the transmission of aerosols. April 2020, Reporters got a cable written by a U.S. diplomat in 2018 Ask for further support for the facility. Cable warned that the lab lacked the proper staff and training needed to safely carry out potentially dangerous research on the coronavirus. According to The Wall Street Journal, the institute does not share data or institute records after the pandemic. Also, the Chinese government does not always publish data from the first day of the pandemic. For example, authorities refused to make raw data on the country’s seasonal diseases available in the fall of 2019.
However, there was little evidence to directly link the Wuhan Institute to SARS-CoV-2. New information about the three sick staff comes from unknown sources. One told The Wall Street Journal that the source was an “international partner” and needed cooperation. Another said that intelligence is “exquisite quality.” A State Department fact sheet released at the end of the Trump administration has already noted reports that lab members became ill in the fall of 2019 “with symptoms consistent with both COVID-19 and common seasonal illnesses.” I was urging, but more specifically, claiming to add a new report.
According to The Wall Street Journal, the Biden administration refused to comment on new information beyond generality. A spokesman for the National Security Council said, “We continue to have serious questions about the early days of the COVID-19 pandemic, including the outbreak in the People’s Republic of China.”
On March 30, WHO called for continued investigation into the origin of the virus. “As far as WHO is concerned, all hypotheses remain at the table,” said Dr. Tedros Adhanom Gebreyes, Director. Said in a statement..
