A committee of the United States Congress has backed the theory that a lab leak caused the COVID-19 pandemic.
In a report released on Monday, the Republican-controlled House of Representatives Select Subcommittee on the Coronavirus Crisis said it had concluded that the coronavirus "likely emerged because of a laboratory or research related accident”.
The 520-page report, which was two years in the making, looked at the federal and state-level response to the pandemic, as well as its origins and vaccination efforts.
"This work will help the United States, and the world, predict the next pandemic, prepare for the next pandemic, protect ourselves from the next pandemic, and hopefully prevent the next pandemic,” Brad Wenstrup, the Republican chairman of the panel, said in a letter to Congress.
Among the report’s headline conclusions was that the US National Institutes of Health (NIS) funded contentious "gain-of-function” research – which enhances viruses to find ways to combat them – at the Wuhan Institute of Virology in China prior to the outbreak.
Cases of COVID-19 were first identified in Wuhan – located in central China’s Hubei province – in December 2019, with the city widely believed to be where the virus first emerged.
