A recent study conducted by a group of Chinese scientists has found that the novel coronavirus, or SARS-CoV-2, has developed into two major types that may have a different transmission capacity and pathogenicity.

Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses have evolved into two major types (designated L and S), according to a paper published on National Science Review on Tuesday.

The findings strongly support the urgent need for further immediate, comprehensive studies that combine genomic data, epidemiological data, and chart records of the clinical symptoms of patients with COVID-19, said the paper.
