Yes, I am very aware it was a pandemic that spread from Asia to Europe. And it did kill people across both continents (as well as in North Africa). It appears to have originated in Central Asia, and migrated West either via the Mongols, the Silk Road, or both. But the effect in Asia was nowhere near as devastating it was in Europe, due to population density. In fact, all of Central Asia had a population in that era of around 12 million. That is smaller than the 17 million that lived in France alone in the same time period. In CHina, some areas were hit hard, especially Hubei province. But the region had already suffered through over a century of famine, and had already had it's population reduced significantly by both famines and other diseases (measles being one of the worst) in the decades prior to this one. We also know it hit the Middle East hard, with a total population loss of around 25%. And a total death rate in the region of around 1 million (the more heavily populated areas of modern Syria and the Gaza Strip were the hardest hit). A far cry from the 5 million lost in England alone. 25% loss in the area, almost 1/3 the percentage lost in much more densely populated Europe. Lower population, lower rate and area of disease spread. Isolated hunter-gatherers and herdsmen have little contact with outsiders, so much less chance to contract the disease in the first place. This is very different than the conditions of Europe. And stand by, here we have some science content coming. The biggest reservoir of diseases appear to keep appearing in China. Higher population densities combined with rainforest and very primitive areas are the perfect incubator for various diseases. We now know that yersinia pestis first evolved over 6,000 years ago, and of the 4 major outbreaks of the disease, every one has been traced back to China. It also can present itself in 1 of 3 different ways, each time being unique to the outbreak. The Pneumonic is one of the most well known, and this was the Black Death of the 14th century. But there is also the Bubonic Plague (large boils), which is what the Plague of Justinian, as well as the Second Plague which came on the heels of the Black Death. Then finally you have the septicemic plague, which is basically an infection of the blood. This was especially seen in the last days of the Black Death. But yea, continue to tell yourself that.
