SARS-CoV-2 Genetic Variant May Be More Transmissible
The so-called 614G mutation in the viral spike protein does not appear to cause more severe cases of COVID-19, but multiple studies indicate that it could be more contagious.

A handful of factors tip the scales in making a virus more likely to trigger a disruptive global outbreak. Right now, scientists tend to rank influenza, coronaviruses, and Nipah virus as the biggest threats.
Analyses of more than 300 ancient human genomes show that Hepatitis B virus has infected humans for at least 4,500 years and has much older origins than modern viral genomes would suggest.
Using epidemiological and laboratory data, scientists have mapped out a sequence of mutations through which the attenuated oral polio vaccine reverts to a virulent virus.
Tracking the genetic diversity and evolution of rhinoviruses can lead to a better understanding of viral evolution, the common cold, and more dangerous infections.
