Understanding the Black Death Today, scientists understand that the Black Death, now known as the plague, is spread by a bacillus called Yersina pestis.

The French biologist Alexandre Yersin discovered this germ at the end of the 19th century. They know that the bacillus travels from person to person pneumonically, or through the air, as well as through the bite of infected fleas and rats. Both of these pests could be found almost everywhere in medieval Europe, but they were particularly at home aboard ships of all kinds — which is how the deadly plague made its way through one European port city after another.

Then it reached Rome and Florence, two cities at the center of an elaborate web of trade routes. Today, this grim sequence of events is terrifying but comprehensible.

Three Major Plague Pandemics

In the middle of the 14th century, however, there seemed to be no rational explanation for it. No one knew exactly how the Black Death was transmitted from one patient to another, and no one knew how to prevent or treat it.

Meanwhile, in a panic, healthy people did all they could to avoid the sick. Doctors refused to see patients; priests refused to administer last rites; and shopkeepers closed their stores.

Many people fled the cities for the countryside, but even there they could not escape the disease: It affected cows, sheep, goats, pigs and chickens as well as people. In fact, so many sheep died that one of the consequences of the Black Death was a European wool shortage.

And many people, desperate to save themselves, even abandoned their sick and dying loved ones. Because they did not understand the biology of the disease, many people believed that the Black Death was a kind of divine punishment — retribution for sins against God such as greed, blasphemy, heresy, fornication and worldliness.

Some people believed that the way to do this was to purge their communities of heretics and other troublemakers — so, for example, many thousands of Jews were massacred in and Thousands more fled to the sparsely populated regions of Eastern Europe, where they could be relatively safe from the rampaging mobs in the cities.

Some people coped with the terror and uncertainty of the Black Death epidemic by lashing out at their neighbors; others coped by turning inward and fretting about the condition of their own souls. Flagellants Some upper-class men joined processions of flagellants that traveled from town to town and engaged in public displays of penance and punishment: They would beat themselves and one another with heavy leather straps studded with sharp pieces of metal while the townspeople looked on.Bubonic plague is the classic form of plague transmitted through the bite of an infected flea.

Bubonic plague victims can expect swollen and painful lymph nodes and the sudden onset of fever. Plague is an infectious disease caused by the bacterium Yersinia pestis.

Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. In the bubonic form there is also swelling of lymph nodes, while in the septicemic form tissues may turn black and die, and in the pneumonic form shortness of breath, cough and chest pain may occur.

The Bubonic plague, which got the name Black Death after there was a pandemic outbreak out of it in Europe during the middle ages, is an infectious disease caused by a bacteria known as Yersinia pestis.

An Introduction to Bubonic Plague Symptoms When a person becomes infected with the bacteria that cause bubonic plague (Yersinia pestis), the bacteria begin to multiply within the lymph system. (The lymph or lymphatic system is a major component of your body's immune system.

The Black Death, also known as The Plague, was a pandemic affecting most of Europe and large swaths of Asia from through that wiped out between and million people in just a few short years.

Caused by the bacterium Yersinia pestis, which is often carried by fleas found on rodents, the plague was a lethal disease that often carried with it symptoms like vomiting, pus-filled.
