New Genetic and Animal Evidence Points to Wuhan Market Origins of COVID Pandemic, but Questions Remain

New research found animal DNA and positive COVID samples at the Wuhan market, suggesting spillover there.
Bats are thought to be the virus's original source, but intermediary animals supplied to the market are still unknown.
The Wuhan Institute of Virology is not ruled out as an origin, though there is no evidence the virus escaped from there.
Limitations like sample timing and market layout leave the exact origin still undetermined.
Further research is needed to pinpoint when and how the virus first spread to humans.
