The origin, spread and virulence of 2019-nCoV remain largely unknown. Most of early infected patients were linked to Huanan seafood wholesale market in Wuhan, China. However,there were 13 of the 41 cases had no link to the marketplace [2]. Most importantly, in the earliest case, the patient became ill on the 1st December 2019 and had no reported access to the seafood market. And no epidemiological link was found between the first patient and later cases. It seems that the seafood market is not the only origin of the virus. The virus probably came into the market place first then it went out of there [12]. Analyses of blood samples in China from people and animals from other animal markets may reveal a clear picture of where the 2019-nCoV originated.
