Coronaviridae

Coronaviridae (pronounced: kuh-roh-nuh-vi-ri-dee) is a family of viruses that cause diseases in mammals and birds. In humans, the viruses cause respiratory infections, including the common cold and more severe diseases such as SARS, MERS, and COVID-19.

Etymology

The name "Coronaviridae" is derived from the Latin corona, meaning crown or halo, which refers to the characteristic appearance of the virus particles (virions) – they have a fringe reminiscent of a royal crown or of the solar corona.

Classification

Coronaviridae is a family in the order Nidovirales. This family is divided into two subfamilies: Orthocoronavirinae and Tobanivirinae. The viruses in these subfamilies are enveloped, positive-sense, single-stranded RNA viruses.
