Expert: Genetic sequencing of virus in Xinfadi suggests it's from Europe

Yang Peng of the Beijing Center for Diseases Prevention and Control says the source of the virus in Beijing's Xinfadi market is still under investigation, but genome sequencing suggests that the virus came from Europe. He said the preliminary conclusion is that the virus was "inbound."

The expert said the exact source of the virus is still unclear. It could be contaminated seafood or meat, or it could be transmitted by secretions from people entering the market.
