    ⚠️Researchers say a mutation (D614G) that occurred in #coronavirus in mid-January increases its spikes and their stability, making it easier to infect cells. The D614G strain now predominates. This strain appears to be more contagious but NOT more lethal.https://www.cnn.com/2020/06/12/health/coronavirus-mutations-scripps-gene/index.html …

        Not surprising though. It certainly appeared, in an intuitive sense, to accelerate in it's spread from the Italian epidemic. Months of seeding from China, didn't begin the US epidemic, but weeks of seeding from Italy appeared to.
