I'm not asserting initialism vs acronyms. I'm talking about the grammar of "Who did".
If you actually meant the World Health Organization, you'd have to interpret that as "World Health Organization did". This is obvious incorrect, and rather should be "The World Health Organization did". So there is no way for your daughter to have interpreted what you said as talking about the World Health Organization, whether initialism or acronym.

No, I wasn't distracted at all. Thanks for the concern, though.
