Factors predicting occult bacteremia in young children.
A febrile child without a definite localizing sign of infection may be in initial phase of bacteremia which unless treated would result in systemic complication. These instances are referred to as "Occult bacteremia". The common pathogens isolated in these children are Streptococcus pneumoniae, Hemophilus influenzae and Neisseria meningitidis. A hundred consecutive children in the age group of 3-36 months attending pediatric outpatient department and casualty were clinically evaluated using AIOS (acute illness observation scale) score and were subjected to complete blood counts, smear for malarial parasites, ESR and blood culture. In the 19-month study period, 4 instances of occult bacteremia were identified. Streptococcus pneumoniae was cultured in 3 cases and H. influenzae in one. A febrile and toxic child in the age group of 3-36 months has a high risk of occult bacteremia. High fever of temperature > or = 102 degrees F, ESR > or = 15 mm/hour, and total leukocyte count > or = 15,000/mm3, in a child with AIOS score of > or = 10 may be considered for more detailed investigations and early intervention with antimicrobial therapy.
