Pneumonia is an inflammatory condition of the lung affecting primarily the microscopic air sacs known as alveoli. It is usually caused by infection involving viruses or bacteria and less commonly caused by other microorganisms, drugs or other conditions such as autoimmune diseases.
Typical signs and symptoms of pneumonia include cough, chest pain, fever, and difficulty breathing. Diagnostic tools include x-rays and a culture of the sputum. Vaccines to prevent certain types of pneumonia are available. Treatment depends on the underlying cause. Pneumonia presumed to be bacterial is treated with antibiotics. If the pneumonia is severe, the affected person is hospitalized.
