Who knows, maybe we're not even the first victims of such fog-related shenanigans in this region.

/ And that's why I said there's at least some chance, not a definite 0. But objectively, it looks like the fog creatures specifically targeted our group and had a specific goal: to kill Sharon. They probably haven't used such a cunning and powerful method in the recent past, so the doctors wouldn't know anything about it. And even if they have, it's not a guarantee that the doctors wouldn't say something like, "Oh, it's some kind of weird thing, very powerful... Well, unfortunately, the patient died then, I don't know how to treat it."
Considering practical logic, in the early stages, in addition to the methods we've already tried, we could have tried to cleanse the intestines of the fungus, but that's not so simple or quick. /

That's why many players develop a fear of every bush.

/ And, I must add, it's still not enough fear of every bush!/
