coughing, or otherwise releasing saliva droplets that are inhaled by another
person. If a person does not get antibiotics within 24 hours of the first
symptoms, pneumonic plague can cause respiratory failure, shock, and rapid
death. Symptoms usually include fever, weakness, and shortness of breath.
Bubonic plague spreads through the bite
of a flea infected with the plague bacterium. Symptoms of bubonic plague
include fever, fatigue, and swollen, tender lymph glands in the neck, armpits,
Septicemic plague occurs when
bacteria enter the bloodstream and multiply. Symptoms of septicemic plague
