How many types of pleagues were there?

Answer 1

Historically, there are three primary types of plague caused by the bacterium Yersinia pestis: bubonic, septicemic, and pneumonic. Bubonic Plague is characterized by swollen lymph nodes called buboes, septicemic plague affects the bloodstream, and pneumonic plague infects the lungs. Each type varies in transmission and severity, with pneumonic being the most contagious. These forms can occur simultaneously in severe cases.
