Practice Gap
The epidemiology of pneumonia is changing; chest radiographs and routine laboratory testing are unnecessary for routine diagnosis of community-acquired pneumonia in children who are candidates for outpatient treatment.
Objectives
The readers of this article are expected to:
Know the cause, clinical manifestations, differential diagnosis, and general approach to the diagnosis, treatment, and prevention strategies of the different types of pneumonia in children of various age groups.
Be aware of the challenges that face the clinician in making an accurate diagnosis of pneumonia due to the inaccuracies and shortcomings of the various laboratory and imaging studies.
Know the complications of pneumonia in children and their appropriate diagnostic and therapeutic strategies.
Introduction
Pneumonia is commonly encountered by emergency department and primary care clinicians. Childhood pneumonia remains a significant cause of morbidity and mortality in developing countries, whereas mortality rates in the developed world have decreased secondary to new vaccines, antimicrobials, and advances in diagnostic and monitoring techniques. (1) This review focuses on pneumonia in children: its causes in various age groups, clinical manifestations, indications for hospitalization, and the challenges that clinicians face in making an accurate diagnosis despite the new and emerging diagnostic tests.
Epidemiology
The incidence of pneumonia varies by age groups and between developing and developed countries. Worldwide, the overall annual incidence of pneumonia in children younger than 5 years is 150 million to 156 million cases, (2)(3) leading to an estimated 2 million deaths per year, most of which occur in developing countries. (4) Forty percent of cases require hospitalization. (5) In developed countries, the annual incidence of pneumonia is estimated at 33 per 10,000 in children younger than 5 years and …
