ALPHA, BETA, gamma, delta. The next letters on the list, if it comes to it, which it probably will, are epsilon, zeta, eta and theta. (B.1.1.7s new name is Alpha.) They will now be given the letters Alpha, Beta, Gamma, and Delta respectively, to reflect their order of detection, with any new variants following the pattern down the Greek alphabet. Currently, there are no plans on how to label the variants after the 24 letters of the Greek alphabet are used up.
