- There are now seven 'variants of concern' and 'variants of interest', each has a Greek letter.
- The Greek alphabet is used to name variants to avoid any stigma associated with naming variants after the countries in which they originated.
- WHO only gives Greek letters to variants of concern and variants of interest.
The current variants of concern are Alpha, Beta, Gamma, Delta and Omicron, while the variants of interest are Lamda and Mu.
"Omicron is spreading at rate that we have not seen with any previous variant. We are concerned that people are dismissing Omicron as mild. Surely we have learned by now that we underestimate this virus at our peril," WHO Director-General Tedros Ghebreyesus warns.
