Covid-19: Could coronavirus mutations be making the disease more infectious?
Mutations in a virus are common in the course of a pandemic, and scientists have discovered thousands of mutations in Sars-Cov-2, the virus that causes covid-19.
Scientists believe that a variant called D614G may have facilitated the transmission of the virus between humans.
And as cases of people being reinfected with covid-19 begin to be observed, there are concerns that this may be the result of new variants. Will we hear more about other mutations in the future?
