Complications of plague may include:

  • Death. Most people who receive prompt antibiotic treatment survive bubonic plague. Untreated plague has a high fatality rate.
  • Gangrene. Blood clots in the tiny blood vessels of your fingers and toes can disrupt the flow of blood and cause that tissue to die. The portions of your fingers and toes that have died may need to be amputated.
  • Meningitis. Rarely, plague may cause an inflammation of the membranes surrounding your brain and spinal cord (meningitis).
