Cecilia Bañuelos, a researcher at the National Polytechnic Institute, talks with Carmen Aristegui about the new variant of coronavirus that the United Kingdom reported, and that, according to specialists, would be more contagious than the previous variants.
Bañuelos assures that viruses by nature tend to mutate, so their impact has to be investigated;
in the case of this variant, the virus becomes more transmissible.
