causes of bubonic plague
Causes of Bubonic Plague: An Overview. Bubonic plague is the most common form of plague. The causes of bubonic plague are bacteria called Yersinia pestis. This bacteria also causes the other two forms of plague: septicemic plague and pneumonic plague (see Types of Plague).ersinia pestis bacteria are usually only found in certain parts of the world, such as Africa, Asia, and South America. Approximately 1,000 to 3,000 cases of bubonic plague are reported each year. Between 10 to 20 of these cases are in the United States, most commonly in rural areas of the Southwest.
Bubonic plague is one of three types of bacterial infection caused by Yersinia pestis. Three to seven days after exposure to the bacteria flu like symptoms develop. This includes fever, headaches, and vomiting.Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin.lague is believed to be the cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people. This was about 25% to 60% of the European population. Because the plague killed so many of the working population, wages rose due to the demand for labor.
