New, more infectious SARS-CoV-2 variant does not cause worse symptoms

Research shows that a new variant of SARS-CoV-2, which is now the dominant form of the virus, is more infectious in cell cultures. However, clinical data suggest that the variant does not cause more severe illness.

All viruses mutate, and the new coronavirus, SARS-CoV-2, is no exception. As an RNA virus, the new coronavirus is highly prone to mutation, partly because the replication enzymes of RNA viruses make more mistakes when copying genetic material.

Although the virus is mutating slowly, scientists had raised concerns that some of the mutations could make the virus more infectious.

One mutation in particular – D614G – has been a focus of concern, as it occurs in the spike protein…
