New names were given to the variants formed by the mutation of the coronavirus virus. In order to prevent ‘geographical stigma’, the World Health Organization (WHO) changed the names of coronavirus variants. The World Health Organization (WHO) suggested that the coronavirus variants that cause Covid-19 be named with letters from the Greek alphabet.

WHO stated that with this new application, it is aimed to prevent both the confusion caused by the variant code consisting of complex letters and numbers, especially in non-scientific discussions, and the stigma of the countries where it was first detected. WHO’s Covid-19 technical team leader Maria Van Kerkhove emphasized that the new names will not replace scientific names in scientific studies and research.


The four coronavirus variants, known around the world as variants of England, South Africa, Brazil and India, have been given the letters Alpha, Beta, Gamma, Delta in the Greek alphabet, in their order. Accordingly, the variant called the British variant is called ‘COVID Alpha’, the variant seen in South Africa is ‘COVID Beta’, the variant common in Brazil is ‘COVID Gamma’ and the variant that spreads in India is called ‘COVID Delta’. It has been recommended.


Alpha: UK, Kent variant – B.1.1.7 – 20I/501Y.V1 – VOC 202012/01

Beta: South African variant – B.1.351 – 20H/501Y.V2

Gamma – Brazilian variant – P.1 – P.1 20J/501Y.V3

Delta – Indian variant – B.1.617
