Recently, three distinct versions of the #coronavirus seem to have independently converged on some of the same mutations, despite being thousands of miles apart in the United Kingdom, South Africa, and Brazil.
The fact that these mutations have popped up not one, not two, but now three times—that we know of—in variants with unusual behavior suggests that they confer an evolutionary advantage to the virus.
All three variants seem to be becoming more common. And all three are potentially more transmissible.
