Strains of Corona virus The corona virus at the root of COVID-19 is the newest known member of this family. At their core ,corona virus contain a genetic blue print called RNA , similar to DNA . The single stranded RNA acts as a molecular message that enables production of protein needed for other elements of the virus. Encapsulating the RNA genome is the viral envelope which protects the virus when it is outside of a host cell . This outer envelope is made from a layer of lipid ,a waxy barrier containing fat molecules. The bulbous projections seen on the outside of the corona virus are spike proteins (red orange). This fringe of proteins gives the virus its crown like appearance under the microscope from which the latin name corona derived.                             Multiple variants of the virus that causes COVID-19 are circulating globally. In collaboration with SARS -COV-2  Interagency Group (SIG) for SARS ...
