Not just the WHO, but also Public Health England, who have advised people against wearing face masks
Public Health England’s guidelines on PPE don’t even match up with the WHO guidelines on PPE. Which is why NHS staff are wearing flimsy bin bag like aprons instead of gowns on the frontline.
It’s convenient that Public Health England recommend the poor PPE they just about have and not the equipment they don’t.
And considering there are NHS staff currently asking for donations of goggles from schools, visiting hardware stores to buy their own masks, nurses and doctors re-using masks multiple times on consecutive days and paramedics arriving to patients without masks at all, I really don’t think the U.K. situation is one to hold up as an example of how to do things correctly.
I’d sooner follow the advice of literally any other country. (except Brazil)
