Pneumonia is an infection of air sacs in the lungs. It can be caused by a virus, bacteria, or a combination of germs.
Severe coughing, throat and chest pain, fatigue, fever, shaking, and shortness of breath are common symptoms. Infections can range from mild to life-threatening, and children and adults over the age of 65 are especially vulnerable.
