Yes, we all know rats can carry disease, and that this has been a historical problem (e.g. the Black Death).
But it's not like coming into physical contact with a rat, or even their droppings or anything, is a common occurrence in NYC.
In 10 years living in New York City, I've seen a rat maybe 50 times total? Every single one was on the subway tracks (i.e. inaccessible), except exactly once I saw one at the end of the deserted platform, but far away from people.
Now I'm sure there are rats elsewhere, I'm just a single data point.
But nevertheless, to put it simply, getting diseases from rats is not a known public health problem in New York City. You cannot extrapolate a risk here simply from the presence of rats.
If you're up for a more disturbing experience, go sit on those benches at the south end of Riverside Park--the ones next to the ivy or whatever. Listen for the squeaking. Guess what? Those are rats. Lots and lots of rats, like in Jurassic Park or something.
Masks?
> I'm not saying New York is a paragon of cleanliness, but you will have to show some scientific evidence that curbside trash pickup or the occasional subway rat has anything to do with the prevalence of modern-day diseases. Because they simply do not as common knowledge suggests.
