You can catch COVID-19 via airborne transmission:

A March 9th story in the South China Morning Press, referencing an article in “Practical Preventive Medicine” which is, AFAIK, published in Chinese, reported that:

The coronavirus that causes Covid-19 can linger in the air for at least 30 minutes and travel up to 4.5 metres — further than the “safe distance” advised by health authorities around the world, according to a study by a team of Chinese government epidemiologists.

The researchers also found that it can last for days on a surface where respiratory droplets land, raising the risk of transmission if unsuspecting people touch it and then rub their face.

The length of time it lasts on the surface depends on factors such as temperature and the type of surface, for example at around 37C (98F), it can survive for two to three days on glass, fabric, metal, plastic or paper.

These findings, from a group of official researchers from Hunan province investigating a cluster case, challenge the advice from health authorities around the world that people should remain apart at a “safe distance” of one to two metres (three to six and a half feet).

I suppose, because the information comes from China, it was ignored by Western medical advisors.
