Close contact transmission
On Feb 19, the National Health Commission issued the latest version of a plan for the diagnosis (诊断) and treatment of the novel coronavirus pneumonia. This is the fifth time that the plan has been revised (修订). Compared to the last version, the new plan has a few changes. For example, it says that the main transmission routes are droplet (飞沫) transmission and close contact transmission, adding “close” before “contact”.
