Coronaviruses (lat. Coronaviridae) is a family of viruses that includes, as of January 2020, 40 species of RNA-containing viruses United in two subfamilies[2] that affect humans and animals. The name is associated with the structure of the virus, whose spiny appendages resemble the solar corona[3]. The purpose of the "crown" in coronaviruses is related to their specific mechanism of penetration through the cell membrane by imitating "fake molecules" of molecules that the transmembrane receptors of cells respond to. After the receptor captures the fake molecule from the "crown", it is pushed by the virus into the cell and the RNA of the virus enters the cell[4][5].
