ALPHA, BETA, gamma, delta. Greek letters are often used as parts of scientific labels, which adds authority to the idea. 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. Epsilon refers to the B.1.427 and B.1.429 variants first found in the U.S., Zeta refers to the P.2 variant first discovered in Brazil and Eta refers to the B.1.525 variant initially detected in multiple countries. The organisation said the labels do not replace existing scientific names involving numbers, Roman letters and full stops, which convey important scientific information and will continue to be used in research.
