Our problem is that our government were caught with its pants down.
They did not have the PPE as it was deemed too expensive to stockpile, after the 2016 government-sponsored exercise to examine our readiness for a pandemic, suggested.
So, in the early weeks of All This; HCPs were 'going in' with no PPE whatsoever. As management had been fed the line that 'it's just flu, relax!' and fed that down.
As a HCP, it was 10-14 days in (with management erstwhile telling us PPE in 'non-symptomatic people' wasn't needed; remember, early days, before national supplies were decimated) before they went....
'Actually, chaps, wear PPE; here's some!'
The reason our government haven't suggested/mandated face coverings, let alone FFP2 or 3, is because They Don't Have Enough.
Which is why there are no Public Health Advisory Messages on telly telling us how to wear them correctly.
