The coronavirus has evolved into two major types, with differing transmission rates and geographical distribution, according to a study published in the National Science Review on Tuesday.

A group of Chinese scientists analysed 103 coronavirus genomes and identified mutations in 149 sites across the strains.
     They found that one type, which they called the L type, was more prevalent than the other, the S type, meaning it was more infectious. They also found that the L type had evolved from the S type, and that the L type was far more widespread before January 7 and in Wuhan, ground zero of the outbreak.
