Currently, there are no plans on how to label the variants after the 24 letters of the Greek alphabet are used up. The B.1.351 variant first found in South Africa was labeled as Beta, the P.1 variant first discovered in Brazil became Gamma and the B.1.617.2 variant first detected in India is now Delta. P.3 first documented in the Philippines is called Theta, B.1.526 first found in the U.S. becomes Iota and B.1.617.1 first discovered in India is labeled as Kappa. As for the desire to avoid hurt feelings, some may consider it oversensitivity. ALPHA, BETA, gamma, delta.
About 10 letters of the Greek alphabet are used.
