"The intelligence community also concurs with the wide scientific consensus that the COVID-19 virus was not man-made or genetically modified."
The statement came after US President Donald Trump suggested on Monday that he might seek damages from China over the outbreak.
News reports say Trump has tasked US spies to find out more about the origins of the virus, at first blamed on a Wuhan, China wet market selling exotic animals like bats, but now thought possibly to be from a virus research laboratory nearby.
Suggesting that Beijing has not been forthcoming about the disease, which has infected about 3.2 million people and killed over 227,000, Trump said Monday that there were many options to "hold them accountable."
"We are not happy with China," he said.
"We are not happy with that whole situation because we believe it could have been stopped at the source."
The US intelligence directorate said it always boosts resources for study and analysis during national security crises.
The intelligence community "will continue to rigorously examine emerging information and intelligence to determine whether the outbreak began through contact with infected animals or if it was the result of an accident at a laboratory in Wuhan," it said.
