Well if rats carry the fleas carrying the plague. LA and Baltimore are off my vacation list. Don’t need no “Ring Around The Rosey” .
U.S. cases of plague are usually in the desert Southwest. Numbers go up during drought, when infected mice and jerboa and stuff move into suburbs looking for irrigation. A few people die from time to time because they didn’t know what they had until too late.
There’s no indication of its being transmitted into urban populations, even in its endemic areas, at this time.
