new Covid-19 The mutation appears to be more contagious, according to a study – and experts say it could be a response from the virus to defeating masks and other social distancing efforts.
In a research paper published on Wednesday, scientists identified a new strain of the virus that constituted 99.9 percent of cases during the second wave in the Houston area of Texas, The Washington Post reported.
The paper, which was not reviewed by colleagues, said people infected with the strain, known as the D614G mutation, had higher amounts of viruses – indicating that it is more contagious.
Although the strain is not the most deadly, the researchers said it appears to have been better adapted to spread between humans.
David Morens, a virologist at the National Institute of Allergy and Infectious Diseases, said the results indicate that the virus may become more contagious and that this “may have implications for our ability to control it.”
He said it is possible that the virus has evolved to resist efforts such as hand washing and social distancing.
Morens told the newspaper: “Wearing masks and washing our hands, all of these things pose barriers to transmissibility or infection, but with the further spread of the virus, it is better statistically to circumvent those barriers.”
