Paris and Janeway were able to be de-salamandered so why didn't Voyager Warp 10 home and let The Doctor fix them?
Obviously the answer is "Because then the show would end" but what in universe?
Maybe all the salamanders want to go to a planet ASAP, and then no one would be piloting the ship to home, no captain doctor yet. They tried it a few times and it ended the same
OR: they realized the bio-neural gel packs on the flyer were also turning into salamanders/ something else? They were only used for the uh, door controls on the flyer, no major systems? They noticed right before they were going to go to warp 10, and saved the crew.
Truly, if Neelix didn't cook those fancy mushrooms from that random off-screen world, they might have gotten home faster.
Even Ex Astris Scientia can't make this one work.

And it's described in LD as that is exactly what happened, so it's hard to get around it.
Well we're at it why didn't they un salamander their babies?
Have Tom's rape babies running around the ship. Awkward.
