Virus travels via wind? | Updated: 2020-02-14 09:09

The major routes of transmission are still through droplets and direct contact, as per the latest explanation released on the WeChat account of China's National Health Commission on Feb 9, 2020. Epidemiological surveys showed most cases could be traced back to close contact with confirmed patients.

The National Health Commission said, for now, the distance for droplet transmission is not rather long, usually shorter than two meters. Droplets with a diameter larger than five micrometers will settle quickly by coughing or during talking, in case of close distance, on mucous membrane of the exposed, resulting in infection. But droplets don't float long in air, and won't be blown far enough to serve as virus carriers.
