Chinese scientists say two types of corono virus could be infecting people

The preliminary study found that a more aggressive strain of the new coronavirus associated with the outbreak in Wuhan accounted for about 70% of analysed cases

Scientists in china, after studying the cause for coronavirus said that  mainly two strains  of the virus are circulating in humans and causing infections.

The researchers, from Peking University’s School of Life Sciences and the Institute Pasteur of Shanghai under the Chinese Academy of Sciences, said that their study looked only at a limited range of data, and further follow ups are needed to check the real evolution and orgin of the virus

The preliminary study found that a more aggressive strain of the new coronavirus associated with the outbreak in Wuhan accounted for about 70 per cent of analysed cases, while 30 per cent were linked to a less aggressive type.

The prevalence of the more aggressive virus type decreased after early January 2020, they said. “These findings strongly support an urgent need for further immediate, comprehensive studies that combine genomic data, epidemiological data, and chart records of the clinical symptoms of patients with coronavirus disease 2019 (COVID-19),” they wrote in a study published on Tuesday in the National Science Review, the journal of the Chinese Academy of Sciences.

Experts not directly involved in the study said its findings were interesting, but cautioned against drawing firm conclusions from it.
