[7] [10] This morphology is created by the viral spike peplomers, which are proteins on the surface of the virus. [11] The scientific name Coronavirus was accepted as a genus name by the International Committee for the Nomenclature of Viruses (later renamed International Committee on Taxonomy of Viruses) in 1971.

Coronaviridae is a family of enveloped, positive-strand RNA viruses which infect amphibians, birds, and mammals.Commonly referred to as coronaviruses in the English language, the family coronaviridae includes the subfamilies Letovirinae and Orthocoronavirinae; the latter also known as coronavirinae.
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
“Similarly, coronaviruses have been known to primarily use bats as their primary reservoir, but with SARS-CoV-2 we saw extensive transmission between other species including humans, deer and ...
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal.
Susan R. Weiss is an American microbiologist who is a Professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania. She holds vice chair positions for the Department of Microbiology and for Faculty Development. [1] Her research considers the biology of coronaviruses, including SARS, MERS and SARS-CoV-2.
The name alphacoronavirus is derived from Ancient Greek ἄλφα (álpha, "the first letter of the Greek alphabet"), and κορώνη (korṓnē, "garland, wreath"), meaning crown, which describes the appearance of the surface projections seen under electron microscopy that resemble a solar corona.
A related coronavirus emerged in Wuhan, China, in November 2019 and spread rapidly around the world. Thought to have originated in bats and subsequently named severe acute respiratory syndrome coronavirus 2, infections with the virus cause a disease called COVID-19, that varies in severity from mild to deadly, [69] and led to a pandemic in 2020.
