Pneumonia facts

  • Pneumonia is a lung infection that can be caused by different types of microorganisms, including bacteria, viruses, fungi, and parasites.
  • Symptoms of pneumonia may include cough with sputum production, fever, sharp chest pain on inspiration (breathing in), and shortness of breath.
  • Children and babies who develop pneumonia often do not have any specific signs of a chest infection but develop a fever, appear quite ill, and can become lethargic.
  • Pneumonia is suspected when a doctor hears abnormal sounds in the chest, and the diagnosis is confirmed by a chest X-ray.
  • Bacteria and fungi causing pneumonia can be identified by sputum culture. In some cases, detection of bacteria causing pneumonia can be done with urine tests (for example, Legionella, Pneumococcus). In others, blood tests demonstrate the body's immune response to certain infections. The results of these blood tests often identify the organism after the patient has recovered.
  • A pleural effusion is a fluid collection around the inflamed lung. This often results when the pneumonia is close to the chest wall and causes inflammation in the pleurae surrounding the lung.
  • Bacterial and fungal (but not viral) pneumonia can be treated with antibiotics and antifungal agents, respectively.
