corona virus (複数形 corona viruses)
出典:『Wiktionary』 (2026/04/01 22:14 UTC 版)
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. Compare the former genus name Coronavirus.
