WHO guidelines for IV bolus for septic shock haven't been updated 2 years since the release of a paper leaving it beyond doubt that children will die more with IV treatment

Why do you think that a single paper leave's something beyond doubt? A lot of papers don't replicate.

There's shitty evidence for the guidelines and we don't know (ok, there's the regular reasons like this why the relevant guidelines aren't evidence based yet given how easy it is to get an infectious disease in Africa...

Why do you use "we"? What do you mean with it?

It might very well be true that you lack the understanding of how the WHO works. While likely a lot of people on LW don't have a strong understanding on WHO internal politics I don't think it's nice to start a post by claiming that your audience is ignorant of a subject (if we is supposed to mean the readers of your post).
