Researchers in China have found that two different types of the new coronavirus could be causing infections worldwide.
In a preliminary study published Tuesday, scientists at Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai found that a more aggressive type of the new coronavirus had accounted for roughly 70% of analyzed strains, while 30% had been linked to a less aggressive type.
The more aggressive type of virus was found to be prevalent in the early stages of the outbreak in Wuhan — the Chinese city where COVID-19 was first detected late last year.
