Bubonic Plague


∙ Recently, a new case of bubonic plague was detected in the USA.

About the Bubonic Plague:

∙ It is often referred to as the ‘Black Death’.

∙ It is an infectious disease caused by the bacterium Yersinia pestis which is usually found in small mammals and their fleas.

∙ It occurs when the bacteria get into the lymph nodes.

∙ Earlier, it occurred from 1346 to 1353, resulting in the deaths of as many as 50 million people in Europe.


∙ Humans can contract the plague in one of three ways:

∙ The bite of infected fleas.

∙ Unprotected contact with infectious bodily fluids or contaminated materials.

∙ The inhalation of respiratory droplets/small particles from a patient with pneumonic plague.


∙ It can cause fever, headache, weakness, and painful, swollen lymph nodes. It usually happens from the bite of an infected flea.

∙ Septicemic Plague: It happens if the bacteria enters the bloodstream, causing abdominal pain, shock, bleeding into the skin, and blackening of appendages, most often fingers, toes, or the nose.

∙ Pneumonic Plague: This is the most dangerous form of the plague, and it happens when the bacteria enter the lungs.

∙ It adds rapidly developing pneumonia to the list of symptoms.


∙ All forms of the plague are treatable with common antibiotics, and people who seek treatment early have a better chance of a full recovery.

∙ Sunlight and drying can kill plague bacteria on surfaces.
