You could interpret this kind of statement as a hardline “never trust anything the government says” stance. You could also interpret it as espousing healthy skepticism.

You can’t tell which it is from a one line comment, so it’s not at all clear the person who said this is buying into any particular political narrative.

I'd call it unhealthy skepticism. Someone who is operating at the level where they might have blindly trusted what the WHO says does not need a push that merely makes them more skeptical of the WHO while remaining hopelessly non-skeptical of all the other manipulators sending narratives their way.
