A few years back, while I was reading Eifelheim, I found myself curious about the timeline of the pandemic and read up on the Black Death. There was an idea floating around at the time that, based on descriptions of the symptoms and spread of the disease, the black death might have been caused by a viral hemorrhagic fever like Marburg, not by the bacteria that causes the bubonic plague that’s still endemic in some parts of the world. Since then, researchers have managed to extract bacterial DNA from the bones of Londoners who died when the plague reached the city in 1348, confirming that they were infected with a relative of the modern plague…and have reconstructed its genome. It’s virtually identical to the modern form.
Wow.
