Is the white blood cell count high in the initial emergency blood test of a child?

When a young child develops roseola, the white blood cell count may be low in the early stages of the disease. If it is a simple roseola infantum, a small number of white blood cells may be high. In addition, when a child cries, the white blood cell count may also increase. When a young child goes to the emergency room, he or she must be treated promptly. Parents should not worry too much at this time as this is a relatively self-limiting disease.

Is the white blood cell count high in the initial emergency blood test of a child?

Roseola infantum is caused by a viral infection, and the white blood cell count is generally normal or low. Simple roseola infantum rarely causes high white blood cell counts, but some babies may have elevated white blood cell counts due to severe crying during blood tests. Roseola infantum, also known as infantile roseola and fever rash, is an acute rash infectious disease common in infants and young children caused by infection with human herpes virus type 6. When the disease occurs, irregular red spots appear on the back, neck and other parts of the body. Mild cold symptoms or persistent high temperature appear within 3-5 days, and a rash appears within 12-24 hours after the fever subsides. For most babies, the symptoms disappear within 1-3 days. The baby will not feel itchy, and it will heal in about a week unless in special circumstances, so there is no need to worry too much.
