Y1 - 2009 N1 - T2 - Pediatric Practice: Infectious Disease AB - The World Health Organization defines pneumonia as the presence of cough and fast or difficult breathing (above 50 breaths per minute for children 2 to 12 months of age; above 40 breaths per minutes for children 12 months to 5 years of age).1 This broad definition may encompass other causes of lower respiratory tract infection including bronchiolitis as well as noninfectious causes of respiratory distress such as asthma. A more specific definition for pneumonia is “the presence of fever, acute respiratory symptoms, or both, plus evidence of parenchymal infiltrates on chest radiography.”2 This definition allows for the possibility of bacterial as well as viral causes of pneumonia.
