The Omicron variant is a variant of SARS-CoV-2, the virus that causes COVID-19. It was first reported to the World Health Organization (WHO) from South Africa on 24 November 2021.[1] On 26 November 2021, the WHO designated it as a variant of concern and named it after omicron, the fifteenth letter in the Greek alphabet.[2][3]

Answer 2

Explanation:

In classical Greek, omicron represented the sound [o] in contrast to omega [ɔː] and ου [oː]. ... The word literally means "little O" (o mikron) as opposed to "great O" (ō mega). In the system of Greek numerals omikron has a value of 70.
