Pneumonia

African-American at doctor.

Pneumonia is a common lung infection caused by germs, such as bacteria, viruses, and fungi. It can be a complication of the flu, but other viruses, bacteria and even fungi can cause pneumonia. Anyone can get pneumonia, but some people are more at risk than others. Pneumonia and its symptoms can vary from mild to severe. Treatment depends on the cause of your pneumonia, how severe your symptoms are, and your age and overall health. Most healthy people recover from pneumonia in one to three weeks, but it can be life-threatening. The good news is that pneumonia can be prevented—by getting an annual flu shot (as flu often leads to pneumonia), frequently washing your hands, and for people at high risk, getting a vaccine for pneumococcal pneumonia. Learn about causes and symptoms of pneumonia, how pneumonia is treated, ways to prevent pneumonia and more in this section.
