A report, published by researchers at the Los Alamos National Laboratory, notes that the rapid and wide spread of Covid-19 provides the virus with “ample opportunity” to mutate in an advantageous way. One particular mutation, called Spike D614G, is “of urgent concern”, according to the authors.
It began spreading in Europe in early February, and quickly became the most dominant form of the virus.
In addition, the report notes that the mutation appears to be replacing the original Wuhan form of the virus.
Scientists noted that although they do not know for sure what is driving the “selective sweep”, the rapid spread would be consistent with “increased infectivity.”
