Answer:
About 75 million people died from the bubonic plague during the 14th century. The disease was spread by fleas from rats. The plague caused high fever, swollen glands, dark bruises or sores on the face, and spitting of blood. Lack of sanitation and poor medical knowledge account for the continuous plague epidemics throughout the 14th century. Most people who got the disease died within five days. Half the population of Italy fell victim to the disease.
