Why Omicron Variant Not Named As Xi – Free PDF Download

What has happened?

  • In picking a name for the newest variant of SARS-CoV-2, Omicron,
  • The World Health Organization (WHO) has skipped two letters of the Greek alphabet, one of which also happens to be a popular surname in China, shared even by Chinese President Xi Jinping.
  • The WHO has been using Greek letters to refer to the most widely prevalent coronavirus variants, which otherwise carry long scientific names.

  • It had already used 12 letters of the Greek alphabet before the newest variant emerged in South Africa this week.
  • After Mu, the 12th named after a Greek letter, WHO selected the name Omicron, instead of Nu or Xi, the two letters between Mu and Omicron.

So what WHO said?

  • The WHO said Nu could have been confused with the word ‘new’ while Xi was not picked up following a convention.
  • “Two letters were skipped —Nu and Xi — because Nu is too easily confounded with ‘new’ and XI was not used because it is a common surname and
  • WHO best practices for naming new diseases (developed in conjunction with FAO and OIE back in 2015) suggest avoiding ‘causing offence to any cultural, social, national, regional, professional or ethnic groups’,” the WHO said in a statement.

What others say?

  • Epidemiologist Martin Kulldorf, a professor of medicine at Harvard Medical School, provided a possible reason.
  • Taking to Twitter, he suggested that the WHO had jumped the alphabet and named the new variant ‘Omicron’ in order to avoid the potential situation of ever having to call a coronavirus variant the ‘Xi’ strain.
  • All things considered, it would be rather awkward for the world to be battling a coronavirus variant that shares its name with Chinese President Xi Jinping, especially after all the debates over the origin of the original virus.
  • But in the bargain, ‘Nu’ lost its claim to fame too!

Why scientific names?

  • All variants are given scientific names that represent their parentage and the chain of evolution.
  • Omicron, for example, is also known by its more scientific designation B.1.1.529, which shows that it has evolved from the B.1 lineage.

  • Since the scientific names are not easy to remember, the more prevalent variants started to be named after the country from where they were first reported: ‘UK variant’, ‘Indian variant’, ‘South African variant’, or ‘Brazilian variant’.
  • To remove the connection with specific countries, which was triggering name-calling and blame game, the WHO decided on a new naming system using Greek letters.
  • The variant that earlier used to be referred as the ‘Indian’ thus got the name Delta, while the one being associated with UK was named Alpha.
