Question

Doctor, recently there have been cases of children experiencing fever symptoms, and upon examination, it was found that their white blood cell count increased. Is this increase due to the fever?

Answer

An increase in white blood cell count is usually associated with acute and chronic bacterial or viral infections, such as acute infections, severe trauma, acute hemorrhage, acute poisoning, leukemia, and malignant tumors. A high white blood cell count typically indicates that the body’s memory cells are responding to inflammation and infection, and may be accompanied by fever symptoms. If the neutrophil count is elevated in the white blood cell count, it may indicate a bacterial infection; if the lymphocyte count is elevated, it may suggest a viral infection. It is recommended to undergo appropriate treatment under the guidance of a doctor.
