The main causes of normal blood count in children but always high fever include the following: First, it is caused by children who have influenza virus. If a child feels the influenza A virus or the influenza B virus, the child’s blood count is in the normal range, but the temperature is very high. The child may also have a headache, sore throat, and muscle aches around the body, and may be treated with oseltamivir. Secondly, Kawasaki disease in children is caused by Kawasaki disease. Kawasaki disease can cause high fever and swollen lymph nodes in children, but the blood count is basically normal because Kawasaki disease is an immune system disease, not an infectious disease, so the blood count is mostly within the normal range. Children can be treated with gammaglobulin at this time.
