If a clothed person has bad hygiene, it will smell bad/make things miserable for a while, but when they leave, the smell should dissipate.
If a nudist has bad hygiene (especially in the bathroom...e.g. doesn't wipe properly, or if they're male they don't, ahem, shake) then that material can potentially be left behind on bus seats (or, if its crowded, on the clothing of people they're pressed up against). I suspect that there would be much less chance of transfer if the individual were wearing at least underwear.
You clearly haven't spent much time on busses frequented by the homeless.
They tend to leave stuff behind regardless of how much clothing they wear.
Yes, I'm sure certain 'dirty' homeless people can leave stuff behind.
However:
- I doubt most homeless people would be going naked anyways. After all, going naked
all the time is impractical, and without a place to store clothes you'd probably have to wear your clothing. Thus, its not just a case of either/or (either naked people or dirty homeless people)... you'd have both the homeless,
and the non-homeless, naked (and perhaps rude) people.
- Even if the homeless decided to go naked, if the person has such bad hygiene to leave stuff behind when clothed, there's a pretty good chance they'd be leaving stuff behind if naked too
My opinion is that as gross as that is, someone farting on a bus seat sans clothing would be worse.
Two words: "Tuberculosis". Read that again.
I happen to live on the edge of one of the worst tuberculosis hot spots in the US. Every wonder why so many cities have laws prohibting spitting on the sidewalk? I'll give you a hint, it's not about the aesthetics.
Good point.
Of course, even in a 'tuberculosis hot spot', not everyone who spits is going to transmit the bacteria. On the other hand, even the healthiest person is capable of leaving behind stains (and dangerous bacteria) from farting
Also, from what I understand (although feel free to correct me if I'm wrong) the disease is transmitted by water droplets at the time of spitting (so, any spit left behind on the floor may not be a problem). On the other hand, any stains left behind from naked people are going to be a problem for a while.
