China has discovered that roughly 14% of patients who recover from coronavirus test positive for the killer disease again – with the mechanism behind the virus’ apparent ability to re-infect a complete mystery.

It is thought that the patients may still be fighting-off lung infections and are not yet completely healthy, Song added.
