Sick baby with low white blood cell count?

The reason I need to know this is a long story, which I don't feel like typing :) But when an infant (12 months) is sick, with a suspected virus, shouldn't their white blood cell count be elevated, because the white blood cells are supposed to fight infection?

But when an infant (12 months) is sick, with a suspected virus, shouldn't their white blood cell count be elevated, because the white blood cells are supposed to fight infection? What would it mean if an infant was sick (cold/flu symptoms, high fever) for 5 days and had a WBC count which was below the normal range for a healthy infant?

Thanks any answers are appreciated.
