No I mean it is a typo on the WHO page, I sent them feedback suggesting this phrasing:

"Wear a mask if you are healthy and you are taking care of a person with COVID-19."

How do you know they made a typo, rather than that's what they meant?

Hanlon's Razor

Perhaps it's neither malice, nor stupidity, but rather... just a different opinion to yours?

It’s a bit presumptuous to assume that the WHO has a typo in a document like this. Besides their messaging has been consistent.

Anyone can make a mistake.

I've worked at large government agencies. These things are reviewed and signed off by dozens of people before posting.

Besides, like I said this is not the only place they've said this. They've been consistent in down-playing the importance of masks.
