Poison and the Epidemic

So I've heard that Poison-Types are completely immune to the infection, though...

I have to wonder if that is only specifically for pure poison-types, or primary poison-types.

There are secondary Poisons out there, and I don't really know if we count primary and secondary types here, but if they are exposed to the epidemic long enough, do you think it would be possible for them to become infected?


If this is already answered somewhere on the site, then sorry >w<

It is for pokemon with Poison as the first and main type if I recall. Thus why tentacruel can be infected

Any pokemon, with the exception of pure poisons can be Infected, regardless of primary or secondary type.

Dual poisons have a high resistance, however, and if Infected, will turn slowly.
