When the World Health Organization decided in May 2021 to use the Greek alphabet to name sars-COv-2 variants, it did so for reasons of simplicity.
The first was Alpha, the second Beta, and so on (although the WHO omitted Nu and Xi because of the potential for homophonic confusion).
But since Omicron became the dominant variant of the virus, new strains have been given names such as BA.4, BA.5 and BA.2.75. But why are none given a Greek name?
The World Health Organization (WHO) argues that, because none of the subvariants result in a significantly different disease than Omicron, they should be classified as “lineages under monitoring” now for
now.
If a strain is highly transmissible, causes severe disease, or evades tests or vaccines, it will be labeled as such.
This makes it eligible for a new Greek denomination.
