Delta coronavirus is a term that has been used to refer to a specific lineage within the larger group of coronaviruses. It is important to distinguish between the general classification of coronaviruses and specific variants or strains that emerge over time. Coronaviruses are a large family of viruses that can cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The term "delta" was notably associated with a significant variant of SARS-CoV-2, the virus that causes COVID-19. This variant, officially designated as B.1.617.2 by the scientific community, emerged in India in late 2020 and subsequently spread globally. The Delta variant was characterized by a set of mutations in its spike protein, which were believed to contribute to increased transmissibility and, in some cases, reduced vaccine effectiveness compared to earlier strains. Its rapid spread led to significant waves of infection in many countries during 2021. While the term "delta coronavirus" might informally refer to this specific SARS-CoV-2 variant, it is crucial to use the official scientific nomenclature when discussing specific viral lineages to avoid confusion. The scientific community continuously monitors and names new variants to track their evolution and impact.
