Another interesting thing is that they have traced back people that have an immunity to HIV have been traced back to places hardest hit by the plague. Both diseases attack white blood cells, so the survivors of the plague might have developed some sort of genetic immunity. I honestly have no knowledge of this type of genetics and I don't remember fully, but this is what I remember and i thought it might interest other people.

Never heard of it ... so I looked it up.

"Several teams of scientists around the world have, for some time, been studying the possibility that a genetic mutation perpetuated by the organism responsible for bubonic plague, or the Black Death, in the Middle Ages - Yersinia pestis - might give people now carrying the mutation increased resistance to the Human Immunodeficiency Virus (HIV) compared to non-carriers."

There's more than a few serendipitous things like this.
1) Once they got rid of smallpox, they stopped giving the vaccine (partly to prevent it reappearing). It turns out people vaccinated against smallpox have some resistance to "mad cow" disease.
2) Just a couple of yrs ago I *THOUGHT* I read an article about how they were thinking or bringing back the smallpox vaccine as a first attempt at one of those tropical diseases now crawling into FL & CA (dengue,zika,chickungunya ... one of those) ... but I can't find a reference. Maybe it was abandoned.
3) Most people know that the sickle cell anemia mutation (originally from the African continent) gives some resistance to malaria. It turns out there's another malaria resistance mutation present in populations from Spain-to-Italy-to-Greece-to-Turkey and around to North Africa (Thalassemia).

That plague article had an interesting kicker. Everyone's been taught FOREVER that Yersinia pestis caused the plague. They did "mathematical analysis" and came up with something else. I *THOUGHT* they had done DNA analysis of bones & came up with Y. pestis. Maybe I'm wrong ... NO! I'm right! Google: "Yersinia pestis DNA" ... lots of articles.

I came upon this video:



and I noticed that certain regions such as northern Scotland didn't get the Bubonic Plague. I guess it was due to the isolation. I have a book on the plague, but it doesn't mention this. Then I saw this video:



Edinburgh is in southern Scotland. What do you think of this? Is it possible that the spread of a plague can be stopped in the same land mass, or did someone make it up?
