asiatimes | Chinese research scientists have released a paper that says the novel
coronavirus known as Covid 19 has mutated into two subtypes.
The latest findings of Chinese scientific researchers allegedly show
that new coronavirus has recently generated 149 mutation points and has
evolved into an L subtype and an S subtype (see map below).
The study found that the two subtypes showed significant differences in geographical distribution and population spread.
The S subtype is a relatively older version, while the L subtype is “more aggressive and more contagious”.
An in-depth understanding of different subtypes will help
differentiate treatment and help prevention of a new strain of
pneumonia, the scientists said.
‘Differ in transmission ability, severity’
The research comes from the paper “On the origin and continuing
evolution of SARS-CoV” published on Tuesday March 3 by the National
Science Review. It was sponsored by the Chinese Academy of Sciences.
Authors of the thesis are researcher Lu Jian, at the Bioinformatics
Center at Peking University’s School of Life Sciences, and researcher
Cui Jie at the Shanghai Pasteur Institute at the Chinese Academy of
Sciences.
The authors believe that, based on the evolution of the new
coronavirus, there may be a large difference in the transmission ability
and severity of disease of the L and S subtypes.
The paper said the difference between the two subtypes is at the 28144 position of the viral RNA genome.
