SARS-CoV-2 Mu variant

The SARS-CoV-2 Mu variant, also known as B.1.621, is a variant of the SARS-CoV-2 virus, which is responsible for the COVID-19 pandemic. The Mu variant was first identified in Colombia in January 2021.

Pronunciation

The term "Mu" is pronounced as /mjuː/, similar to the English word "mew". The term "SARS-CoV-2" is pronounced as /ˈsɑːrz koʊ viː ˈtuː/.

Etymology

The variant is named after the 12th letter of the Greek alphabet, "Mu". The naming follows the World Health Organization's (WHO) decision to name variants of SARS-CoV-2 after letters of the Greek alphabet to avoid stigmatization associated with naming the variants after the locations where they were first identified.

Characteristics

The Mu variant has a number of mutations that potentially allow it to evade the immune response, although further research is needed to confirm this. The WHO has designated it as a variant of interest (VOI).
