The document summarizes information about the Bubonic Plague, including that its incubation period is 2-6 days through airborne transmission and symptoms include abdominal pain, bloody cough, fever and swollen lymph nodes. It killed an estimated 25-60% of Europeans and up to 200 million people worldwide in the 1300s. While antibiotics can treat it, the plague remains difficult to eradicate as it can infect animals and is still present today in some parts of Africa, Asia, and the United States, though better hygiene has reduced its infectiousness.
