Pneumonia is a disease that causes the air sacs in the lungs to fill with pus or fluid, making it difficult for oxygen to reach your bloodstream. You can develop this disease in one of your lungs or in both lungs at the same time. This illness can be mild or very serious. You may also have pneumonia without knowing it, called walking pneumonia. It is easier to get pneumonia if you are younger than two or older than 65 because your immune system is weaker.

In the 19th century, people discovered that illness was not just symptoms of other illnesses, but that it was a disease in itself. After that, Edwin Klebs, a German pathologist, examined the bacteria causing pneumonia for the first time under a microscope. This happened in 1875. Carl Friedlander and Albert Frankel determined which two bacteria were most likely to cause pneumonia in the 1880s. By the 1930s, many ways to combat pneumonia had emerged, but the disease remained very common and fatal. In the United States, approximately 423,000 people are diagnosed with pneumonia each year. These diagnoses were made after a person went to the emergency room with serious symptoms. This disease is so common and dangerous that 66.9% of people over 65 have been vaccinated against pneumonia. The number of deaths of people over 65 is 50,622 people per year. This is a dangerously high number. Additionally, pneumonia kills 16% of children under five. In 2015, the disease caused the deaths of 920,136 children. 15.9 people out of 100,000 die from pneumonia. Although pneumonia is very deadly, it has also been treated in many people before.

He was then put on strong antibiotics. Eight days later his fever was gone, which was a good sign. After 27 days he was finally released. This is the story of a serious case of pneumonia that could have been fatal if it had not been treated as quickly as it was.
