China has additional scientific data that allows a better understanding of the origins of covid-19the World Health Organization (WHO) assured on Thursday in yet another call for more transparency from the Asian giant on this issue.

“Without full access to the information that China has (…) all hypotheses (about the origin of the coronavirus) are still on the table. This is the position of the WHO and therefore we ask China to cooperateTedros Adhanom Ghebreyesus, director general of this UN agency, said at a press conference in Geneva.

“If he does, we’ll know what happened and how it started.”he added.

“We know that (China) has additional information and we need scientists, public health professionals and governments to share this information. This is not a game,” said Dr Maria Van Kerkhove, who leads the fight against Covid-19 at WHO, during the same performance.

Three years after the appearance of covid-19, debates about the origins of the pandemic continue.

Most of the scientific community believes the coronavirus originated from an animal that transmitted it to a human, likely at Huanan Market in the east-central Chinese city of Wuhan.

However, American scientists and leaders defend the hypothesis that a leak occurred in a laboratory in the same city in the Asian giant. China opposes this theory, but has long denied that there were any animals in the Huanan market that could have transmitted the virus.

However, according to new Chinese data, published in late January and quickly suppressed, there is molecular evidence for the sale of animals in the marketplace. “We had our doubts about it, but now we have proof,” said Van Kerkhove.

“We also know that among the samples positively diagnosed with SARS-Cov-2, there was DNA from animals,” he added. But as long as not all scientific data are available, according to this American epidemiologist, any hypothesis about the origin of covid-19 cannot be ruled out.
