Linguistics
Semantic Notes
The term is an initialism for 'Severe Acute Respiratory Syndrome Coronavirus 2'. It refers specifically to the virus itself, whereas 'COVID-19' refers to the disease caused by the virus. In non-technical contexts, it is often used interchangeably with 'the coronavirus' or 'the COVID-19 virus'.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'SARS-KoB-2' using Cyrillic sounds. Use the English acronym pronunciation.
- Avoid calquing the structure; it is a proper noun, not a descriptive phrase in English.
Common Mistakes
- Writing 'SARs-COV-2' (incorrect capitalisation).
- Saying 'SARS-CoV-2 disease' (the disease is COVID-19).
- Omitting the hyphen or using a space: 'SARS CoV 2'.
- Pronouncing 'CoV' as /kɒv/ instead of /ˈkəʊv/ or /ˈkoʊv/.

FAQ
Frequently Asked Questions
No. SARS-CoV-2 is the name of the virus. COVID-19 is the name of the disease caused by that virus.
It is pronounced as a single syllable: /ˈkəʊv/ in British English and /ˈkoʊv/ in American English, rhyming with 'cove'.
The hyphen is standard in taxonomic names for viruses. It separates the subgenus (SARS-CoV) from the strain number (2).
Typically, it is used as an uncountable proper noun (e.g., 'infection with SARS-CoV-2'). In highly technical contexts, you might see 'SARS-CoV-2s' referring to multiple distinct variants or lineages.
