Presentation
A 34-day-old white boy presents to the emergency department with a fever (101.8°F [38.8°C]) and a 1-day history of poor feeding and fussiness. There is no other history of acute illness, although his older brother currently has oral ulcers secondary to a viral illness. He was born at term after an uncomplicated pregnancy. Maternal prenatal infection screening, including group B Streptococcus, was negative. He was discharged on the second day after birth and had been breastfeeding with good weight gain until the day before admission.

Neurologic examination demonstrates normal tone and strength, and there are no focal deficits. The remainder of the physical examination findings are normal.
Laboratory studies are significant for a white blood cell count of 2,800/μL (2.8×109/L), with an absolute neutrophil count of 180/μL (0.18×109/L). Results of cerebrospinal fluid (CSF) studies show a total protein level of 0.118 g/dL (1.18 g/L), glucose level of 56 mg/dL (3.1 mmol/L), white blood cell count of 13/μL (0.013×109/L), and red blood cell count of 0.052×106/μL (0.052×1012/L). The Gram-stain showed no organisms. Herpes simplex and enterovirus polymerase chain reaction (PCR) results are negative. The remainder of the laboratory …
