In order to identify the etiology of fever with out source in children treated at emergency department of Hospital del Niño and relate laboratory results obtained with bacterial infection. A prospective observational cohort study was conducted in one hundred patients who attended with fever, and which failed to identify a source of infection. The main results the most common diagnoses were uncomplicated upper respiratory infection and urinary tract infection, 11 patients were classified with severe bacterial infection. The degree of fever greater than 39° and the like lihood of bacterial infection was presented with a RR of 0.8 (95% CI 0.42-1.82). The association of leukocytosis > 15.000/mm³and bacterial infection showed a RR of 3.32 (95% CI 2.06-5.34). Partnering with ANC > 10.000/mm³had an RR of 3.17 (95% CI 2.23-4.49), and band neutrophils > 500/mm³a RR of 2.38 (1.07-3.33 95%). This study ratifies the findings identified in similar studies, found as major predictors of bacterial infection leukocytosis > 15.000/mm³, the ANC > 10.000/mm³ and band neutrophils > 500/mm³.

Palabras clave : fever without source; bacterial infection.
