Thats correct .. actually the US contribution to WHO is/was $116M or about 24%
This is typical, you see I knew all their dirty tricks of creative accounting (as I'm a chartered certified accountant). It was my lecturer who shown me what the West do when quoting figures. Ever since then, I always fact check.
They are very subtle, they don't want to be accused of outright lying, so there's always that wiggle room they left for themselves to weasel out of it!
I remember they always quote the Soviet arm spending as per national income (never capita or absolute). In that way it makes them look bad.
And with the WHO funding, it's very clever to club in all the charity and NGO's together to inflate it. And technically they are right as money is all from within the USA. Further they also knew, no ordinary public will ever bother to fact check them, because of their built in trust for their government. After all why would their government lie?!
