Evidence suggests the coronavirus originated in bats in China in late 2019 and was not made in a laboratory, the World Health Organization said Tuesday.

The comment from the United Nation's health agency comes days after President Donald Trump said the U.S. was trying to determine whether the virus originated from a lab in Wuhan, China.

"All available evidence suggests the virus has an animal origin and is not a manipulated or constructed virus in a lab or somewhere else," WHO spokeswoman Fadela Chaib told a news briefing in Geneva, Reuters reported Tuesday.

"It is probable, likely that the virus is of animal origin," she said, adding that there had "certainly" been an intermediate animal host before the virus was transmitted to humans.

Current and former U.S. intelligence officials told NBC News last week the country's intelligence community was examining whether the coronavirus emerged accidentally from a Chinese lab studying diseases in bats. The lab in question has denied the accusation, calling it a "conspiracy theory."
