Highly contagious double mutant Indian variant responsible for current surge of Covid-19 cases

A WHO collaborating centre in India confirmed that all samples of the infected people belong to B.1.617, known as double mutant variant, which is highly infectious and possibly more lethal.

The highly infectious, and possibly more lethal, sub-lineages of double mutant variants of the coronavirus, known as B.1.617.2, and B.1.617.1 have been found to be responsible for the current surge in the new cases throughout the country.
