China virus: mutations chain

A virus found in bats may be the common ancestor of the SARS virus and the new coronavirus found in China scientists say. The new virus has passed from the bat to one or more animals, not yet identified, where it has undergone one or more mutations (concerning the strain responsible for SARS, it was found in a civet). These mutations made it transmissible from animal to man, and then it was found to be also transmissible from human to human.
