Etymology:
The word "corona" is derived from the Latin word "corona," which means "crown" or "wreath." It has been used in various contexts throughout history, particularly in reference to the circular structures surrounding celestial bodies.
Meaning and Origin:
In the context of viral infections, the term "corona" specifically refers to the distinctive ring or halo-like structure that surrounds the virions (virus particles) when observed under an electron microscope. This structure is composed of spike proteins that protrude from the surface of the virion and resemble a crown or a sunflower.
The coronavirus that causes COVID-19 (SARS-CoV-2) was identified in late 2019. It was named based on its characteristic corona-like appearance. The virus has four main types of structural proteins, including the spike proteins that form the corona. These spike proteins play a crucial role in the virus' ability to bind to and enter host cells.
The term "corona" has been used historically to describe similar structures observed in other viruses. For example, the virus that causes the common cold (human coronavirus) also has a corona-like appearance. However, the term "corona" is now most commonly associated with the virus that causes COVID-19 due to the global pandemic it has caused.
