Aerosolization of coronavirus seems to be mostly limited to hospital operations such as intubation?

Anyhow, here in Hong Kong the virus has been, kind of, contained. Mask wearing, along with hand washing and other measures, have been adopted by the majority population.

One of the problems with the Wuhan virus is that there are quite a few asymptomatic cases, and AFAIK at least one preprint study has confirmed that these hosts can transmit the virus to others, making mask wearing for "healthy" people an even more desirable measure in preventing the virus from spreading.
