The US has relatively low levels of food borne diseases. It was an example.
Also parasites, like hookworm:

Up to a quarter of a billion people are infected worldwide, in large part due to poor hygiene.
Then there's round worm, likely a billion people infected globally. Once again, due to poor sanitation and hygiene aka handwashing.

Just know that at this point you might as well stick your thumb up a strangers ass then lick it. It's fundamentally not that different to not caring about washing off shit particles before eating food.
Hyperspace in Star Wars is ridiculously fast, true. The empire/republic is also huge because of this. We're talking millions of worlds. Absurdly large.
It's the same thing in Asimov's Foundation (which everyone should watch, the second season is excellent) where the galactic empire spans the entire milky way. Population is 500 quadrillion apparently.
