Pneumonia in the Lungs
An infection that occurs in one or both lungs, pneumonia is a common but potentially serious condition that can be caused by bacteria, viruses, or other germs. Common symptoms include chills, fever, fatigue, and phlegm-producing cough. This disease can occur in people of all ages, and is more common in people who smoke.
Most people with pneumonia can treat the lung infection at home with rest, fluids, and possibly antibiotics (these are used for bacterial cases only). However, people with more severe symptoms may need treatment in the hospital.
Typically, it takes about three to five days before a person with pneumonia starts to feel better. It can take three weeks or more before a person feels well enough to resume his or her normal routine. Fatigue and a mild cough can last for a month or more.
