Covid-19: US says it has new evidence coronavirus may have come from a Chinese laboratory
- Virus ‘could have emerged naturally … [but] a laboratory accident could resemble a natural outbreak if the initial exposure included only a few individuals’, US Department of State says
- But brief, unsigned statement provides no data to back up its claims
Specifically, the US Department of State said it had obtained evidence that researchers at the Wuhan Institute of Virology became sick in the autumn of 2019 – before the first identified case was identified in the city – with symptoms it said were consistent with either Covid-19 or common seasonal illnesses.
China’s lack of transparency about the pandemic’s origin more than a year ago, as well as efforts to mask early shortcomings in the country’s response to the outbreak, made it difficult to draw clear conclusions, it said.
But the brief, unsigned statement, issued just days before Trump leaves office, provided no data to back up its claims.
“The virus could have emerged naturally from human contact with infected animals, spreading in a pattern consistent with a natural epidemic,” it said. “Alternatively, a laboratory accident could resemble a natural outbreak if the initial exposure included only a few individuals and was compounded by asymptomatic infection.”
China has repeatedly rejected charges that the virus might have emerged from a laboratory. The US did not say how it obtained the new information about illnesses at the lab.
