Recurrent fever and normal blood counts in children are usually caused by viral infections, tuberculosis infections and other conditions. 1. Viral infections: children with recurrent fever and normal blood counts may be caused by viral infections, and some patients with viral infections may also have headaches, sore throats, and muscle aches and pains. 2. Tuberculosis infection: tuberculosis infection may also lead to recurrent fever and normal blood count in children, and patients with tuberculosis infection are usually accompanied by prolonged low-grade fever, sweating, night sweating (sweating abnormally after going to sleep, and sweating stops after waking up), and emaciation and other symptoms. Children with recurrent fever and normal blood counts may have other causes, so it is recommended that they go to the hospital in time for a complete examination to determine the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
