Not true. We have it already in America. Lots of fleas among the prairie dogs. Hanta virus which is from fleas also is far more dangerous but rarer and also lives in the Southwest. Curing it is chancy while Plague is eminently curable if one doesn’t wait until dead to get to a medic.
Brain fart. Hanta virus is from rat droppings,not fleas and there is acase or two of that in the SW every now and then.
