Coronavirus #31: To mask or not to mask

With increasing cases of the highly contagious Delta variant in the UK, there is concern that making masks voluntary on 19 July will simply make things worse.

Masks are more about protecting others from expelled virus than protecting yourself, but their impact is limited and they are not themselves a substitute for other measures like test-and-trace, self-isolation and physical distancing where possible. From my own observation, a lot fewer people are wearing masks than used to be and I am sure many of them don't have exemptions.

Public compliance and goodwill have largely gone; Matt Hancock's antics were a final straw, I would wager. 

For my part, I intend to do as Professor Chris Whitty has advised after the 19th; I will wear a mask when asked or when I can't physically keep my distance from others. I'm double jabbed anyway and also do twice-weekly lateral flow tests, which I doubt is common.
