What is community-acquired pneumonia?

Community acquired pneumonia is a common disease with a reducing incidence. It usually occurs in children or the elderly,

or in people with an underlying pathology. Streptococcus is the most common bacterial cause of community-acquired pneumonia. Other causes of community-acquired pneumonia include Haemophilus influenzae, Legionella, mycoplasma, chlamydia, and viruses. Staphylococcus may rarely cause community-acquired pneumonia, but this organism is more often a cause of hospital-acquired pneumonia. Community-acquired pneumonia occurs most commonly in very young and very old people. Typical symptoms of community-acquired pneumonia include cough, purulent sputum production, shortness of breath, pleuritic chest pain, fevers and chills. On examination, one notes rapid respiratory rate and heart rate and signs of pulmonary consolidation. In the elderly, symptoms and signs are vague and non-specific. They may consist of headache, malaise, diarrhea, confusion, falling, and decreased appetite. Diagnosis is confirmed by chest x-ray. In general, patients who present with what appears to be CAP, with findings confined to the lungs and no laboratory evidence of extrapulmonary involvement, have CAP caused by a typical pathogen. Patients who have pneumonia plus extrapulmonary physical findings or laboratory features (such as elevations in liver function test results) have an atypical pneumonia.

What is walking pneumonia? - Walking pneumonia is pneumonia that is usually mild enough that the child does not have to stay in bed.
What is aspiration pneumonia? - Aspiration pneumonia is an inflammation of the lungs and bronchial tubes caused by inhaling foreign material.
What is bacterial pneumonia? - Bacterial pneumonia is pneumonia caused by bacteria. Streptococcus pneumoniae is the most common cause of bacterial pneumonia.
What is viral pneumonia? - Viral pneumonia is caused by various viruses. Viral pneumonia is usually milder than bacterial pneumonia.
What is bronchial pneumonia? - Bronchial pneumonia is when the pneumonia spreads to several patches in one or both lungs.
What is community-acquired pneumonia? - Community-acquired pneumonia occurs most commonly in very young and very old people.
What is hospital-acquired pneumonia? - Hospital-acquired pneumonia, also called nosocomial pneumonia, is an infection that patients get while they're in the hospital.

What're the complications of pneumonia? - Complications of pneumonia that may occur include buildup of fluid in the space between the lung and chest wall.
What are the symptoms of pneumonia? - Symptoms of pneumonia are shortness of breath, chest pain, coughing, shallow, and fever and chills.
How is pneumonia diagnosed? - The diagnosis of pneumonia is usually made from a medical history, a physical examination, and a chest X-ray.
What's the treatment for pneumonia? - Treatment of pneumonia consists of respiratory support, including O2 if indicated, and antibiotics.
How to prevent pneumonia? - Vaccines are available to protect against pneumococcal pneumonia, pneumonia caused by the bacterium.
