TOKYO -- The new coronavirus likely began spreading in China last fall, according to separate analyses of its genome by research teams in the U.K. and elsewhere.

These analyses, which cover all genetic information of the virus, indicate ongoing person-to-person transmission before the first patient was confirmed in the Chinese city of Wuhan. But no clues confirm where the virus came from or how it came to be, leaving an even deeper mystery.
