Signs and Symptoms
The most infamous symptom of bubonic plague is an infection of the lymph glands (lymphadenitis), which become swollen and painful and are known as buboes. After being transmitted via the bite of an infected flea the Y. pestis bacteria become localized in an inflamed lymph node where they begin to colonize and reproduce. Buboes associated with the bubonic plague are commonly found in the armpits, upper femoral, groin and neck region. Acral gangrene (i.e. of the fingers, toes, lips and nose), is another common symptom.
Due to its bite-based form of infection, the bubonic plague is often the first step of a progressive series of illnesses. Bubonic plague symptoms appear suddenly, usually 2–5 days after exposure to the bacteria. Symptoms include:
- Acral gangrene: Gangrene of the extremities such as toes, fingers, lips and tip of the nose.
- Chills
- General ill feeling (malaise)
- High fever (39 °Celsius; 102 °Fahrenheit)
- Muscle Cramps
- Seizures
- Smooth, painful lymph gland swelling called a buboe, commonly found in the groin, but may occur in the armpits or neck, most often at the site of the initial infection (bite or scratch)
- Pain may occur in the area before the swelling appears
- Skin color changes to a pink hue in some very extreme cases
Other symptoms include heavy breathing, continuous vomiting of blood (hematemesis), aching limbs, coughing, and extreme pain. The pain is usually caused by the decay or decomposition of the skin while the person is still alive. Additional symptoms include extreme fatigue, gastrointestinal problems, lenticulae (black dots scattered throughout the body), delirium and coma.
Two other types of Y. pestis plague are pneumonic and septicemic. Pneumonic plague, unlike the bubonic or septicemic, induces coughing and is very infectious, allowing it to be spread person to person.

“The LORD brought us out of Egypt with a mighty hand and an outstretched arm, with a terrifying display of power, and with signs and wonders; and he brought us into this place and gave us this land, a land flowing with milk and honey.”
—Bible: Hebrew, Deuteronomy 26:8.
“Young children scare easily—a tough tone, a sharp reprimand, an exasperated glance, a peeved scowl will do it. Little signs of rejection—you don’t have to hit young children to hurt them—cut very deeply.”
—James L. Hymes, Jr. (20th century)
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
