From the Tele (their main story). Yes, it does appear to contradict itself somewhat!
Coronavirus has mutated into two strains, one which appears to be far more aggressive, scientists have said, in a discovery which could hinder attempts to develop a vaccine.
Researchers at Peking University's School of Life Sciences and the Institut Pasteur of Shanghai, discovered the virus has evolved into two major lineages - dubbed ‘L’ and ‘S’ types.
The older ‘S-type’ appears to be milder and less infectious, while the ‘L-type’ which emerged later, spreads quickly and currently accounts for around 70 per cent of cases.
Genetic analysis of a man in the US who tested positive on January 21, also showed it is possible to be infected with both types.
...
The Chinese scientists, who analysed the viral DNA from 103 infected people, said it appeared the less dangerous ‘S-type’ was now taking over, possibly because of aggressive public health lockdown measures in China, which had stopped the more virulent disease in its tracks.
