info about Coronavirus

The name "coronavirus" is derived from the Latin corona, meaning crown or halo, and refers to the characteristic appearance of virions (the infective form of the virus) under electron microscopy (E.M.) with a fringe of large, bulbous surface projections creating an image reminiscent of a royal crown or of the solar corona. This morphology is created by the viral spike (S) peplomers, which are proteins that populate the surface of the virus and determine host tropism.

Corona viruses are species of virus belonging to the subfamily Coronavirinae in the family Coronaviridae, in the order Nidovirales.Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and with a nucleocapsid of helical symmetry. The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus.
