Chinese scientists discover two major subtypes of Covid-19

BEIJING (China Daily/ANN): Chinese scientists have discovered the novel coronavirus has evolved into two major subtypes. Experts believe investigating the differences and features of these subtypes may help evaluate risks and formulate better treatment and prevention plans.

The two subtypes are named L and S. The L type is more aggressive and was prevalent in the early stages of the outbreak in Wuhan, Central China's Hubei province. But instances of the S type, which is older and less aggressive, have increased in frequency recently, thus possibly explaining the disease's slowing momentum in China.
