This article is a bibliographic review, since coronaviruses originate from the Latin name “corona”, which in turn is a word taken from the Greek “κορώνη”, which means crown or garland.
They are large pleomorphic spherical particles, with bulbous surfaces, the average diameter of the envelope is 80nm (nanometers) and the spicules (or beaks) are 20nm long. The envelope consists of a double layer of lipids (fats), where three types of structural proteins are anchored (the membrane type M, the envelope type E and the spike type S); however, another subset of coronavirus has another surface protein, called HE, of hemagglutinin esterase.
In humans, they were discovered in 1960, in patients with the common cold (or so the human doctors of the time thought). They named them human coronavirus 229E and human coronavirus OC43 and the first photo taken of both viruses was taken by Scottish virologist June Almeida (virologist), at Saint Thomas Hospital in London. Since that time, SARS-CoV in 2003, JCoV NL63 in 2004, HKU1 in 2005, MERS CoV in 2012 and SARS-CoV-2 in 2019 (COVD 19) have appeared; most of them having serious respiratory infections.
