Pneumonia
Pneumonia is also called viral pneumonia, community-acquired pneumonia, or simple pneumonia. It is caused by one of several viruses including varicella (chickenpox), influenza, and adenovirus.
Pneumonia is not a single disease, but the name for several types of lung inflammation caused by infectious organisms. Pneumonia is the sixth most common cause of death in the U.S., primarily because it is a common complication of any serious illness. It is more common in males, during infancy and old age, and in those who have reduced immunity to infection. The symptoms, treatment, and outcome vary greatly, depending on the cause and on the general health of the patient.
Symptoms may include fever, headache, chills, weakness, chest pain, and a cough that produces sputum and occasionally blood. Potential complications include pleural effusion (fluid around the lung), empyema (pus in the pleural cavity), and, rarely, an abscess in the lung.
