We propose that the new coronavirus which first appeared in the Hubei province of China was probably linked to the arrival of a pure culture of the virus contained in cometary debris that was dispersed over a localised area of the planet namely China. The sighting of a fireball some 2000 kilometers north of Wuhan on 11 October 2019 followed shortly after with the first recorded cases in Hubei is suggestive of a causal link. Gene sequencing data of the virus that show little or no genetic variations between isolates, combined with available epidemiological data point to the predominance of a transmission process directly from an “infected” environment, with personto- person transmission playing a comparatively weaker secondary role. The facts relating to this epidemic are discussed and placed in the context of other pandemics that have been recorded throughout history.
