Corona loss is due to ionisation of the air coulumn sorrounding the conductor, due to distortion in the electric field pattern around the conductor. This distortion in the field pattern in gasseous medium is given by streamer theory. This distortion causes lots of miniature localised breakdowns in the surrounding air column due to which you can expect a violet glow and a hissing noise. Two kinds of respiratory transmission are through large droplets, which is thought to be short-range, and airborne transmission on much smaller particles over longer distances.
In times of crisis, the government of the day has a responsibility to downplay alarm and fear in order to avoid a panic situation where the crises would be difficult to manage, as in the case of the Coronavirus outbreak. The downplay should not be interpreted as a “cover-up”, as Prof Minxin Pei has alluded to in his article below. Prof Minxin Pei is a Professor of Government at Claremont McKenna College and a non-resident senior fellow at the German Marshall Fund of the US. In his article in J&M entitled “The Coronavirus is a Disease of Chinese Autocracy” he alleged that the Chinese Communist Party (CCP) suppressed the news of the Coronavirus outbreak.
