This 1975, digitally colorized transmission electron microscopic (TEM) image, depicted four human coronavirus 229E particles, which are members of the Coronaviridae family. Coronaviruses possesses a helical genome, composed of non-segmented, positive-sense single-stranded RNA ((+) ssRNA). This is an enveloped virus, which means that its outermost covering is derived from the host cell membrane. The coronavirus derives its name from the fact that under electron microscopic examination, each virion is surrounded by a corona, or halo, due to the presence of viral spike peplomers emanating from its proteinaceous envelope.
