The new COVID variant has been named “Omicron”. To be more precise, it has been renamed as “Omicron” from “Nu”. Someone recently brought this up in a conversation, and I realized that I did not know much about this.

So, I decided to do some research and answer my own curious questions. If you’re curious about this topic as well, just read along.

Why Was the New COVID Variant Called “Nu” in the First Place?

To begin understanding the reasoning behind the renaming, we need to answer this question first. It turns out that we name each newly discovered COVID (SARS-CoV-2) variant after a Greek alphabet. So far, the most prominent COVID variants have been called alpha, beta, gamma, delta, etc.

The deciding authority that came up with this naming convention is the World Health Organization (WHO).
