History and Etymology for coronavirus

corona + virus, later taken as New Latin

Note: The word was introduced by a group of virologists as a short article "Coronaviruses" in the "News and Views" section of Nature (vol. 220, no. 5168, November 16, 1968, p. 650): "…avian infectious bronchitis virus has a characteristic electron microscopic appearance resembling, but distinct from, that of myxoviruses. Particles are more or less rounded in profile…there is also a characteristic 'fringe' of projections 200 Å long, which are rounded or petal shaped, rather than sharp or pointed, as in the myxoviruses. This appearance, recalling the solar corona, is shared by mouse hepatitis virus….In the opinion of the eight virologists these viruses are members of a previously unrecognized group which they suggest should be called the coronaviruses, to recall the characteristic appearance by which these viruses are identified in the electron microscope."
