Well, there have been cases of the plague here in the US, but they weren't caused by immigrants....................
Bubonic Plague Still Kills Thousands
In the United States during that time period, 56 people contracted the plague and seven died. The cases occurred mainly because plague has become endemic in squirrels and wild rodents in the American West. Two of the fatalities were scientists: one who had conducted an autopsy on a wild mountain lion, and another who worked with plague bacteria in the lab.
Specifically, we are not talking about the plague in the context of immigrants. It's not clear that the mere photographs of the problem are enough to convey the enormity of the seminal cause of a plague vector.
It's not immigrants except as they add to the number of homeless or as they add to the number of people dumping household, business or restaurant garbage in the streets. Last year we only had homeless. This year we have homeless and huge garbage piles. The garbage is relatively new. Are people dumping in the streets because they are immigrants who don't have a concept of trash collection or because they can't or won't pay for trash collection?
All of this trash, rotting food, garbage, feces and dead animals has attracted legions of rats. The rats carry untold billions of fleas and that is where disease is developed.
We had typhus and got assurances that it was nothing to worry about. Any complaints was at least borderline racist. Then typhoid fever closed city hall. Liberals address bubonic plague by saying it is nothing more than a mild cold easily cleared up with antibiotics.
