Explain the cause of the bubonic plague and how to cure it and when it started and who discovered the cure to it in simple english

The bubonic plague is caused by a bacterium called Yersinia pestis. It is typically spread through fleas that live on rats, and it can also spread from person to person through respiratory droplets. The disease is famous for causing massive outbreaks in history, especially during the Black Death in the 14th century.

The bubonic plague usually causes swollen and painful lumps called "buboes," fever, chills, and weakness.

To treat the bubonic plague today, antibiotics are used. If caught early, the infection can be treated effectively, and most people recover with the right medication. Doctors may also provide supportive care, such as fluids and pain relief.

The plague was first recognized in history during an outbreak in the 6th century, but the most notorious event, known as the Black Death, began in 1347 and lasted for several years, killing millions across Europe and Asia.

The discovery of antibiotics in the 20th century significantly improved the ability to cure the plague. Although many people contributed to the development of antibiotics, Alexander Fleming is often credited with discovering penicillin in 1928, which led to the development of many antibiotics used to treat various infections, including the bubonic plague.

In summary, the cause of the bubonic plague is a bacterium spread by fleas, and it can be treated with antibiotics discovered in the 20th century. The plague was historically significant, especially during the 14th century.
