I'm currently (though not at this moment) watching a Great Courses series on the Black Death. One point that's been brought up both in the course and in my reading is that, although we're pretty darn sure that Yersinia pestis is "Bubonic Plague," we're not nearly as sure that there weren't other causes of death kicking around at the same time.

Also, the lecturer wears very slimming outfits, which I will copy if I'm invited to appear on "Jeopardy!".

It appears the flea-borne virus is more preferable, maybe that’s why Los Angeles is breeding them

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.

It was in vogue a few years back to deny Y. Pestis as the cause of The Plague, but DNA research has taken a chain saw to that silly notion. But yeah, there are always different causes of death, and most of them have come and gone a few times, due to non-human reservoirs. Smallpox emerged perhaps no more than 3K years ago, and has no known non-human host -- the eradication program worldwide has worked -- the CDC says no cases since 1980. The Egyptian 18th Dynasty pharaohs' mummified remains have survived for the most part, and the non-invasive study (CAT scans and whatev') have shown the lesions on at least two of them.

Well that’s nice to know. I still wouldn’t go to LA or Baltimore if Nasty Pelosi and Cummings paid for the trips. As a kid I spent time shooting rats. I bet the locals in either location wouldn’t appreciate that. We’ll see if the poem comes back, history has a way of repeating itself.

The lecturer said that the experience of England with the Black Death suggests anthrax was going on at the same time, described in contemporaneous sources as “a cattle murrain.”

Plague is very treatable if it’s caught early. Should it appear in an urban setting in the U.S. today, it would have a different profile than in, say, 1347 Florence.

Diagnosis was pretty sophisticated even before the emergence of microbiology.

The pneumonic form of plague is directly human-to-human contagious, so the jump to fleas may have been a lateral species jump providing another disease vector and an additional reservoir in infected animals. Cheery thought - what we have today is the new, improved version.

Regarding this snip of the original excerpt up top:
The Books of Samuel in the Bible describe an outbreak of plague among the Philistines in 1320 BC, complete with swellings in the groin, which the World Health Organization has argued fits the description of bubonic plague. Mirazón-Lahr suggests this may support the idea of a Middle Eastern origin for the plague's highly lethal genetic evolution.
Philistines keyword, edited, chrono sort:

Smallpox started as a mutation from a rat-borne bug of some sort.

Yes, but there’s a lot of ground between the 14th century and microbiology, and documentation doesn’t always make stuff clear.

Read years ago that during the time of the Black Death there was an colder than normal period bringing the rats in closer to humans.

Thank God we have global warming!!!

There was a heavy rain spell with subsequent famine. The really cold hit in the late 1500s.

The cold-so-rats-move-in theory for the Black Death has taken some hits, but the population-crunch theory is still holding water.
