This 1975 transmission electron microscopic (TEM) image shows human coronavirus 229E particles. Coronaviruses possess a helical genome composed of 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. For a colorized version of this image see PHIL 15523.
