Perspectives on SARS-CoV-2 strains

SARS-CoV-2, the virus responsible for the ongoing pandemic, is changing as it spreads throughout the world. However, the assertions about a more aggressive strain spreading across human populations is merely conjecture at this point. It is necessary to conduct rigorous studies that couple clinical data (such as patient features and outcomes) with changes in the virus, as well as laboratory studies that test the effect of mutations on the ability of the virus to replicate and spread. Without this evidence, it is speculative to assign spread and disease severity to mutations. This brief examines the claims that changes in the genome of the SARS-CoV-2 virus are making it spread faster or increasing its virulence.
