Pneumonia is an infection of one or both of the lungs
Pneumonia is named based on the type of germ that is infecting the patient.
Community-acquired pneumonia (CAP) occurs in group settings, such as dorm room and hospitals.
Lung infection causes the alveoli, or air sacs, to become inflamed. The air sacs may also fill up with fluid or pus.
Pneumonia symptoms can vary from mild to severe based on the type of germ only.
Pneumonia is only more serious if the person also has HIV/AIDS or is undergoing chemotherapy or an organ or bone marrow transplant.
Everyone with pneumonia needs to be treated in the hospital.
You can prevent pneumonia with a vaccine.
