What are the symptoms of pneumonia?

The most common symptoms of pneumonia are shortness of breath; chest pain, especially when breathing in; coughing; shallow, rapid breathing; and fever and chills. Coughs usually bring up mucus, also called sputum. The sputum may even

be streaked with blood or pus. In serious cases, the patient's lips or nail bed will appear blue due to lack of oxygen. Physical examination may detect tachypnea and signs of consolidation, such as crackles with bronchial breath sounds. This syndrome is commonly caused by bacteria, such as S. pneumoniae and H. influenzae. People who have bacterial pneumonia usually are very sick. Symptoms of bacterial pneumonia usually begin suddenly and often develop during or after an upper respiratory infection, such as influenza or a cold. Symptoms of viral pneumonia are often less obvious, less severe, and come on gradually. Viral pneumonia often goes unrecognized because the person may not appear very ill. The symptoms vary with age and whether the person has other health problems. Pneumonia caused by anaerobic bacteria such as Bacteroides can produce dangerous abscesses in the lungs. People with such pneumonias may have prolonged fever and productive cough, frequently showing blood in the sputum. Signs of blood may indicate dead lung tissue (necrosis). About a third of these patients experience weight loss. Older adults may have milder symptoms, such as a dry (nonproductive) cough. Sometimes there may be no fever. A change in mental status (confusion or delirium) or worsening of an underlying lung disease may be the major sign of pneumonia in older adults.

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.
