Findings from the World Health Organization (WHO) and China's joint investigations into the root cause of COVID-19 provided little in terms of concrete proof on how the pandemic began -- an indication that scientists believe may take years to determine.
WHO food safety scientist Ben Embarek noted that the investigation is "only the start" of a meticulous, comprehensive process. He said investigators have just merely "scratched the surface" of a "very complex set of studies that need to be conducted."
COVID-19 "Likely" to Have Originated in Bats

It also debunked rumors that the coronavirus emanated from a lab in China, saying it was "extremely unlikely," further said in an NBC News report.
