American epidemiologist criticizes conspiracy theories about COVID-19 origin

An American epidemiologist criticized conspiracy theories about the origin of COVID-19, saying that many questions have yet to be answered. The epidemiologist Devra Davis refuted such a fallacy, saying the virus has developed from the mutation of a virus in bats, rather than somewhere else. She also said the U.S. government has failed to provide an unified response policy, which has led to states to respond to the virus on their own.
