It is named SARS-CoV-2 because of its similarity to the earlier virus SARS-CoV, responsible for the SARS disease.

This virus was formerly known as 2019-nCoV, meaning "2019 novel coronavirus", before being assigned the present name by the International Committee on Taxonomy of Viruses.

This virus is a positive-sense single-stranded RNA virus.

Sars-Cov-2 is a word used to describe Covid-19, the seventh coronavirus. SARS found a way to become better into, SARS the Second and then everyone realised that and used that for Covid. Coronavirus was named a Crown Virus so people might falsely assume that it is asserting supreme dominance, but it is not.

Person 1: And how bad was Sars-CoV-2?

Acronym for Severe Acute Respiratory Syndrome related Corona Virus 2, the two relating to the fact that it seems more closely related to the original SARS coronavirus than the MERS (Middle East Respiratory Syndrome) coronavirus was.

The unnecessarily confusing, obnoxious, and irritating name—also known as SARS2—made up by some genius for the virus caused by COVID-19 because apparently someone ran out of names.
Scientist 1: “This virus is getting out of hand! And we don’t have a proper name! God help us!”
Scientist 2: “How about SARS2?”
Scientist 1: “Excellent idea! Now let’s just add CoV so it doesn’t sound like a movie sequel.”

Scientist 2: “SARS-CoV-2 it is then.”
Scientist 1: “INGENIOUS! NOMINATE THIS MAN FOR THE GOD POSITION!”
