Three forms of the plague brought an array of signs and symptoms to those infected: Bubonic plague refers to the painful lymph node swellings called buboes, primarily found around the base of the neck, in the armpits and groin which oozed pus and bled.
Victims underwent damage to the skin and underlying tissue until they were covered in dark blotches. Most victims died within four to seven days after infection. When the plague reached Europe, it first struck port cities and then followed the trade routes, both by sea and land. Of those who contracted the bubonic plague, 4 out of 5 died within eight days. The pneumonic plague is an airborne plague that attacks the lungs before the rest of the body.
Pneumonic plague was the second most commonly seen form during the Black Death with a mortality rate of ninety to ninety-five percent. The septicaemic plague is a form of deadly blood poisoning. The disease is contracted primarily through the bite of an infected insect. Septicemic plague can cause disseminated intravascular coagulation, and is almost always fatal; the mortality rate in medieval times was percent. Septicemic plague is the rarest of the three plague varieties.
Rats The bubonic plague mechanism was dependent on two populations of rodents: one resistant to the disease, which acts as hosts, keeping the disease endemic; and a second that lacks resistance. When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic. The original carrier for the plague-infected fleas thought to be responsible for the Black Death was the black rat.
The bacterium responsible for the Black Death, Yersinia pestis, was commonly endemic in only a few rodent species and is usually transmitted zoonotically by the rat flea.
Brown rats may suffer from plague, as can many non-rodent species, including dogs, cats, and humans. Let us know what you learn. Definitely, Eric!

The reason why Medieval doctors dressed up like birds. It should be pretty obvious that the appearance is not simply coincidental. In fact the earliest plague Doctor uniforms were modeled after a mythical bird called "Caledrini" which was purported to have the ability to cure various diseases.
Medieval people were much less involved with science, but the medieval bestiary was a way of conveying symbolism to people.
