  Because, to repeat myself, there is evidence that surgical masks used by a trained (in the use of masks and in proper behaviour around the sick) clinicians in a clinical setting do have efficacy. These trained people in an entirely different setting than the ones your are advocating their use in by untrained people will also: - not reuse masks - remove masks correctly and at appropriate times - dispose of masks correctly - engage in several other related behaviours that will prevent transmission World of difference.
