Bubonic Plague

Bubonic plague, also known as bubonic plague, is a form of plague caused by the bacterium Yersinia pestis. It gets its name from the characteristic swellings of the lymph nodes (buboes) that appear in the groin, armpits or neck of infected people and animals.

The bacterium Y. pestis is carried by fleas, usually from infected rodents such as rats. When a flea bites a person, the bacteria can enter the bloodstream. It migrates to the nearest lymph nodes, where it multiplies, causing inflammation and the formation of buboes. The buboes can become very painful and reach the size of a grapefruit.

Symptoms of bubonic plague include fever, chills, headaches, muscle pain and buboes. Without treatment, mortality can reach 50-90%. However, with timely treatment with antibiotics such as streptomycin, mortality is reduced to 10-15%.

Bubonic plague has been responsible for three major pandemics in the past, including the Black Death in the 14th century, which is believed to have killed an estimated 50 million people in Europe and Asia. Today, bubonic plague remains endemic in some parts of the world, particularly in Africa, Asia and South America, and continues to pose a threat to public health. However, thanks to improved sanitation, rodent control, and the availability of effective antibiotics, outbreaks of bubonic plague are relatively rare and contained. However, the disease remains dangerous and it is important to conduct surveillance and respond quickly to any outbreaks to prevent its spread.

Bubonic plague, also known as septicemic plague, is one of the most terrible and destructive epidemic diseases that has ever affected humanity. This is an infectious disease that is caused by the bacteria Yersinia pestis, and is spread through contaminated droppings of rodents, insects or from an infected person.
