“The possible origins of 2019-nCoV coronavirus”
Botao Xiao1,2* and Lei Xiao3

In summary, somebody was entangled with the evolution of 2019-nCoV coronavirus. In addition to
origins of natural recombination and intermediate host, the killer coronavirus probably originated
from a laboratory in Wuhan. Safety level may need to be reinforced in high risk biohazardous
laboratories. Regulations may be taken to relocate these laboratories far away from city center and
other densely populated places.
