Pneumonia

Common Name(s)

Pneumonia

Pneumonia is an infection of the air sacs in one or both lungs. The air sacs may fill with fluid or pus causing fever, chills, and difficulty breathing. A variety of organisms can cause pneumonia including bacteria, viruses, and fungi. Pneumonia can range from mild to life threatening. It is usually most serious in infants and young children, people older than age 65, and people with weakened immune systems.

Symptoms of pneumonia may include fever, lower than normal body temperature in people older than 65, cough, chest pain, shortness of breath, fatigue and muscle aches, nausea, vomiting or diarrhea, and headache. Newborns and infants may not show any sign of the infection. Pneumonia is classified according to the types of germs that cause it and where the infection was acquired. The different classifications include community-acquired pneumonia, hospital-acquired pneumonia, health care-acquired pneumonia, and aspiration pneumonia.

Infants and children younger than age 2 and people older than age 65 are at a higher risk of pneumonia. Other risk factors include certain chronic diseases, such as asthma and heart disease, weakened immune system, smoking, and being placed on a ventilator. Complications of pneumonia may include bacteria in the bloodstream, lung abscess, fluid accumulation around the lungs (pleural effusion), and difficulty breathing. If your doctor thinks you have pneumonia, they may recommend chest X-rays, blood tests, pulse oximetry, sputum test, pleural fluid culture, and bronchoscopy to diagnose. Treatment involves curing the infection and preventing any complications. Treatment options depend on the type and severity of your pneumonia, but may include antibiotics, antiviral medications, fever reducers, cough medicine, and hospitalization if serious. If you or a family member has been diagnosed with pneumonia talk with your doctor and specialist about the most current treatment options.
