Researchers in China say preliminary research shows that COVID-19 is mutating and there are at least two types of the virus now. One of those, the more aggressive strain, has infected 70% of the people tested for the virus.
According to doctors at Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai, a less aggressive strain of the virus has infected the other 30% of those who have contracted COVID-19. Scientists have called the aggressive strain “L type” and the less prevalent version “S type.” The L type strain was seen more frequently in Wuhan, where the outbreak began, but researchers note that the frequency of infection has dropped off. They also cautioned that the data they had available for study was “very limited” and they still don’t fully understand the evolution of this virus.
