But for general purposes, journalism included, the simplicity of beta is probably betteras is alpha for B.1.1.7, etc, the so-called Kent or UK or British variant, gamma for P.1, etc, (the Brazilian variant) and delta for B.1.617.2 (the Indian variant). The World Meteorological Organization Hurricane Committee said it would discontinue the use of the Greek alphabet to name hurricanes. 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. While they have their advantages, these scientific names can be difficult to say and recall, and are prone to misreporting, the WHO said in a statement.
The B.1.375 variant found in South Africa was identified as Rotletter.
