A more infectious version first overtook the OG coronavirus last spring, before giving way to the ultra-transmissible Alpha (B.1.1.7) variant. Now Delta (B.1.617.2), potentially the most contagious contender to date, is poised to usurp the global throne.
Alphabetically, chronologically, the virus is getting better and better at its primary objective: infecting us. And
