Coronaviridae is a family of enveloped, positive-sense, single-stranded RNA viruses. The viral genome is 26–32 kilobases in length. The particles have large (~20 nm), club- or petal-shaped spikes on the surface (the "peplomers" ). The particles in electron micrographs look like the solar corona.
The family Coronaviridae is has 2 sub-families, 5 genera, 26 sub-genera, and 46 species.[1] More species are possible, but not yet confirmed.[2]
