[Harry Potter] Are Muggles sent to St. Mungos? What if they need an 'extended stay'?

As far as I know, St. Mungos is for magical related illnesses and injuries, but I've never heard if Muggles go there or not if they get hit with something magical somehow.

And what if an 'extended stay' is needed? Something like what happened with Nevilles parents might not warrant a stay there (possibly a Muggle mental health facility), but something that might take weeks/months to cure/treat...that is, if there is anything they can get affected with that lasts that long.

Yes, muggles go to ST. Mungos, if they are magically afflicted. There is a specific ward set aside that looks like a normal hospital, but staffed by witches and wizards with specialties in both muggle care, and memory charms.

There is a separate facility for long-term magical mental health patients. A witch or wizard with mental health problems can be extremely dangerous, even without a wand (the ability of underage wizards to cast spells in times of emotional distress proves the point that wands are focuses, not sources of power. Because deteriorating mental health can make for extreme emotional distress, it is necessary to have an extremely locked-down facility, with spell-absorbing walls, in addition to basic precautions.
