I definitely laughed at that Darth Vader comment. I now wish that the prequels' explanation for why he's in that suit was, in fact, that he's a germophobe.
It's never explained in-universe, unless the explanation is in one of the numerous books of the extended universe. The movies certainly don't talk about it. That's the kind of detail that they aren't really interested in in what is essentially a fantasy film set in space.
I'd imagine there are sterilizing rooms coming in and out of places like Cloud City. Maybe there are some on spaceships. Like, every time they walk up or down the ramp on the Falcon they get de-bugged. Ships and cities might scan people for new virus strains, too.
Alternatively...
Maybe from an evolutionary perspective every species in Star Wars only survives because they all have hyper-power immune systems which respond unbelievably fast compared to what we've got.
Additionally, it's likely that, given the diversity of species in the Star Wars universe, species are beset by their own set of illnesses. In real life, viruses that jump species only happen when living in *close* proximity (ie: a one-bedroom apartment where you keep chickens without cages). As long as Han and Chewie have the whole Falcon to live in, the virus won't make the jump.

Yeah, that's exactly what I was wondering - I tell you one thing, I bet this has been explained somewhere in Star Trek's extended book universe!

In Star Trek, they'd scan you with "biometrics" or something if you come in via shuttlecraft. The transporter weeds out viruses. I know this because there are a couple episodes where they get space flu or whatever and there's always a line of dialogue about how the transporter must've missed that one.
