[Community acquired pneumonia in children: an update for outpatients management].

Pneumonia should be considered in febrile children with tachypnea and/or chest recession. Virus are the most common cause of pneumonia in children under 5 years old. Streptococcus pneumonia can be found at any age. Mycoplasma pneumonia is more frequent in older children. Systematic chest radiograph is not necessary but must be obtained in patients with hypoventilation and in those with failed initial antibiotic therapy. Mycoplasma pneumonia should be tested according to patient age and response to initial antibiotic. First line antibiotherapy is amoxicilline. Antibiotic treatment is frequently not necessary in children under 5 but should be considered depending on clinical presentation and C reactive protein value.
