Bats are also thought to be the ultimate reservoir of coronaviruses, but the virus has also been isolated from snakes and palm civets, a game animal resembling a cat prized by the Chinese for its heat-giving energy. The SARS epidemic was almost certainly sparked by civets traded at a wild animal market in Shenzhen in southeast China. Likewise, the Wuhan outbreak appears to have begun at a wholesale seafood market which, despite its name, also sold wild animals, including wolf cubs, crocodiles, snakes and bats.
