Bubonic plague transmission usually occurs in one of three ways:
- Direct contact with infected tissue or bodily fluids
- Bites from infected rodent fleas
- Inhaling infected droplets.
When a person becomes infected with the bacteria that cause bubonic plague, the bacteria begin to multiply within the body. This occurs in the lymph system. Also known as the lymphatic system, this is a major component of your body's immune system. The organs within the lymphatic system are the tonsils, adenoids, spleen, and thymus. Symptoms of the bubonic plague can begin within one to six days of being infected. The period between becoming infected and the start of plague symptoms is called the bubonic plague incubation period.
It is possible for a person to first develop bubonic plague symptoms, followed several days later by septicemic plague symptoms, and then pneumonic plague symptoms.
