The World Health Organization announces a new system of naming the COVID-19 variants using the Greek alphabet in order to avoid stigmatizing countries where variants are first detected. According to the new system, B.1.1.7 becomes Alpha, B.1.351 becomes Beta, and P.1 becomes Gamma. Meanwhile B.1.617, which split into sub-lineage B.1.617.1 and B.1.617.2, is called Kappa and Delta respectively.
