A new study confirms that the SARS-CoV-2 coronavirus has mutated in a way that has enabled it to spread quickly around the world.
The new strain of coronavirus, called D614G, emerged in Europe and has become the most common in the world, according to researchers at the University of North Carolina at Chapel Hill and the University of Wisconsin-Madison.
These researchers believe the D614G strain of coronavirus dominates because it increases the spike protein's ability to open cells for the virus to enter.
This study published in Science on November 12, 2020, shows the D614G strain replicates 10-times faster and is more transmissible than the initial SARS-CoV-2 that spread globally during early 2020.
"The D614G virus outcompetes and outgrows the ancestral strain by about 10-fold and replicates extremely efficiently in primary nasal epithelial cells, which are a potentially important site for person-to-person transmission," said Ralph Baric, professor of epidemiology at the UNC-Chapel Hill Gillings School of Global Public Health and professor of microbiology and immunology at the UNC School of Medicine, in a related press release.
