Infants have slightly higher white blood cell counts than adults, but they are considered normal if there are no symptoms. No treatment is needed if there are no symptoms. An elevated white blood cell count suggests the possibility of inflammation. If you have a cold, it’s important to consider this, so I recommend you go to the hospital for further examination and consider whether there are allergic symptoms. Generally, under such symptoms, it’s best not to worry too much and to proceed with anti-inflammatory treatment. I suggest you seek treatment at a reputable professional hospital.
