The researchers, from Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai under the Chinese Academy of Sciences, said the study found that a more aggressive strain in Wuhan accounted for 70% of analysed cases, while 30% were linked to a less aggressive type. The prevalence of the more aggressive virus type decreased after early January, they said.
