The implications are profound. We need to stop the 'infection control theatre' of putting round sticky patches 2 metres apart, assuming any object is a fomite (i.e. transmits the virus) and repeatedly gelling hands. 3/

Precautions for *airborne* infection in health/care settings include a) VENTILATION, b) reducing time spent in rooms with other people, c) high-grade PPE even when NOT doing AGPs, d) ensuring that *everyone* is masked for source control unless over-riding reason not to. 4/

These are matters of life and death. As a healthcare worker and the parent of a HCW, and having attended funerals of HCWs who died in the course of their work, I ask you to read the paper at the start of this thread and help support AIRBORNE precautions in health/care settings./5
