Accuracy of Clinical and Diagnostic Studies for Pneumonia in Children

We will collect clinical history for each patient (days of illness, history of fever, cough, difficulty breathing, vomiting, chest pain).

We will collect physical exam findings including vital signs, WHO criteria for diagnosing pneumonia, and lung auscultation findings.

We will collect laboratory findings (white blood cell counts, differential, and c-reactive protein) if ordered by the clinician.

We will perform lung ultrasound on all patients.
