Pneumonia is an infection deep in the lungs. Here is an overview of pneumonia to help you provide proper first aid for pneumonia.
Pneumonia is an infection deep in the lungs affecting small air sacs called the alveoli. Pneumonia is most often caused by bacteria. About a third of the cases of pneumonia in the U.S. come from viruses.
Pneumonia can follow a cold or the flu. The signs and symptoms of pneumonia come from both the infection and the reaction in the lungs, which interferes with air flow.
The most important treatment for pneumonia is to recognize the symptoms of pneumonia and contact your doctor. Pneumonia treatment often requires antibiotics or other prescription medications, depending on the cause of the pneumonia. Pneumonia treatment at home focuses on treating the cause and coping with the symptoms, especially shortness of breath.
