Former head of China's CDC says there is no evidence COVID-19 came from an animal and jumped to humans
Former head of the Chinese CDC says there is no evidence yet showing which animal the COVID-causing virus may have come from.
Dr. George Fu Gao, director of the Chinese Center for Disease Control and Prevention, believes the origins of COVID-19 will not be revealed.
Gao claims that the subject is too sensitive and politicized, and that the focus should be on science.
He also stated that there is no evidence of an intermediate animal species between bats and humans.
