What spreads the Black plague?
Plague bacteria are most often transmitted by the bite of an infected flea. During plague epizootics, many rodents die, causing hungry fleas to seek other sources of blood. People and animals that visit places where rodents have recently died from plague are at risk of being infected from flea bites.

Mortality rates for treated individuals range from 1 percent to 15 percent for bubonic plague to 40 percent for septicemic plague. In untreated victims, the rates rise to about 50 percent for bubonic and 100 percent for septicemic.
