From corona (“crown-like circle of light appearing around the sun”) + virus. Corona is derived from Latin corōna (“garland, wreath; crown”), from Ancient Greek κορώνη (korṓnē, “something curved; curved stern of a ship; end, point, tip”), from Proto-Indo-European *(s)ker- (“to bend, turn”). The name refers to the characteristic appearance of its virions by electron microscopy, which have a fringe of surface projections creating an image reminiscent of a solar corona.
