Avian Flu Diary: Study: SARS-CoV-2 D614G Variant Exhibits Efficient Replication Ex Vivo and Transmission in Vivo

While this D614G variant appears more easily transmitted than its parental strain, it does not seem to cause any worse illness in humans. It may, however, partially explain why Western nations have had less success in containing COVID-19 than has China, Taiwan, and Japan.

This latest report by researchers at the University of North Carolina at Chapel Hill and the University of Wisconsin-Madison, confirms (using animal studies) that this variant is not only more infectious, it replicates 10 times faster than its ancestral strain.

While a more transmissible virus is never a good thing, the news isn’t all bad, as the researchers suggest this variant may be slightly more susceptible to vaccines currently under development.
