Pneumonia is a lung infection that causes inflammation and the buildup of mucus and fluids in the lungs. This may cause coughing and difficulty breathing. Community-acquired pneumonia is pneumonia that develops in people who are not, and have not recently been, in a hospital or other health care facility.
Usually, pneumonia develops as a result of an illness that is caused by a virus, such as the common cold and the flu (influenza). It can also be caused by bacteria or fungi. While the common cold and influenza can pass from person to person (are contagious), pneumonia itself is not considered contagious.
If your pneumonia is severe, other tests may be done to learn more about the cause.
Treatment for this condition depends on many factors, such as the cause of your pneumonia, your medicines, and other medical conditions that you have.
These symptoms may represent a serious problem that is an emergency. Do not wait to see if the symptoms will go away. Get medical help right away. Call your local emergency services (911 in the U.S.). Do not drive yourself to the hospital.
