  • No evidence COVID came from animals

    Author: AAP

There is no evidence that the COVID-causing virus came from animals, the former head of the Chinese Center for Disease Control and Prevention (CDC) says.

George Gao, who was speaking at a London summit on preparing for pandemics, was the head of the agency when COVID first emerged in Wuhan, China, at the end of 2019.

"Even now, people think some animals are the host or reservoir," said Gao. "Cut a long story short, there is no evidence which animals (were) where the virus comes (from)."

The origins of the COVID-19 pandemic remain unknown, with criticism that China has thwarted efforts to find out more. The Chinese government has said it has always supported all efforts to investigate the source.

The World Health Organisation has said that all hypotheses for the origins of COVID-19 remain on the table, including that the virus is linked to a high-security laboratory for the study of dangerous pathogens in Wuhan.


China denies any such link.

WHO has also said the evidence so far points towards the virus coming from animals, likely bats.

Data from the early days of the pandemic was uploaded to a global database by Chinese scientists last month.

It included genetic sequences found in more than 1000 environmental and animal samples taken in January 2020 at the Huanan seafood market in Wuhan.

The data showed that DNA from multiple animal species - including raccoon dogs - was present in environmental samples that tested positive for SARS-CoV-2, the virus that causes COVID, suggesting that they were "the most likely conduits" of the disease, according to a team of international researchers.
