BEIJING — China is rejecting allegations that the coronavirus pandemic may have originated in a laboratory near the city of Wuhan where contagious samples were being stored.

Foreign Ministry spokesman Zhao Lijian cited the head of the World Health Organization and other unidentified medical experts as saying there was no evidence that transmission began from the lab and there was “no scientific basis” for such claims.

“We always believe that this is a scientific issue and requires the professional assessment of scientists and medical experts,” Zhao told reporters at a daily briefing on Thursday.

“Only with reasonable response can the international community win this fight,” Zhao said. “China will continue to work together with other countries to help and support each other.”

China has also strongly denied claims it delayed reporting on the virus outbreak in Wuhan late last year and underreported case numbers, worsening the impact on the U.S. and other countries. The virus is widely believed to have originated with bats and have passed via another animal species to humans at a wildlife and seafood market in Wuhan, although a firm determination has yet to be made.

Allegations about a leak of the virus from the lab have been made in the U.S. media without direct evidence, and President Donald Trump has vowed to suspend funding for the World Health Organization, partly because of what he claims is its pro-China bias.

  2. More probably, “the shit is out of the [crazy] bat.”

  3. Trump now owns the IC. I don’t accept without proof a word they say anymore. And the rest of the world has great scientists to keep them honest. This is QAnon crap.

    Clinching the case for nature

    But then the researchers compared SARS-CoV-2 with other coronaviruses recently found in nature, including in bats and pangolins. “It looks like SARS-CoV-2 could be a mix of bat and pangolin viruses,” Garry says.

    Viruses, especially RNA viruses such as coronaviruses, often swap genes in nature. Finding genes related to the pangolin viruses was especially reassuring because those viruses’ genetic makeup wasn’t known until after SARS-CoV-2’s discovery, making it unlikely anyone was working with them in a lab, he says.

    pangolin

    Coronaviruses that infect pangolins gave researchers important clues that the SARS-CoV-2 virus is natural.

    In particular, pangolins also have the amino acids that cause the tight binding of the spike protein to ACE2, the team found. “So clearly, this is something that can happen in nature,” Andersen says. “I thought that was very important little clue. It shows there’s no mystery about its tighter binding to the human [protein] because pangolins do it, too.”

    The sugar-attachment sites were another clue that the virus is natural, Andersen says. The sugars create a “mucin shield” that protects the virus from an immune system attack. But lab tissue culture dishes don’t have immune systems, making it unlikely that such an adaptation would arise from growing the virus in a lab. “That sort of explained away the tissue-culture hypothesis,” he says.

    Similarity of SARS-CoV-2 to bat and pangolin viruses is some of the best evidence that the virus is natural, Hodcroft says. “This was just another animal spillover into humans,” she says. “It’s really the most simple explanation for what we see.” Researchers still aren’t sure exactly which animal was the source.

  4. If anyone’s interested in the science behind comparative virology, I recommend a piece in Current Biology from 10 days ago:
    Probable Pangolin Origin of SARS-CoV-2 Associated with the COVID-19 Outbreak

  5. Best way to eradicate the DrumpfenVirus 16 is to shelter it in place until it burns itself out. I would suggest the same for the Epstein/Barr virus, as half of that was eradicated through isolation from the public.
    Also, any offspring viruses must be dealt with to make sure they don’t create a secondary infection after the host is gone.
