When high white blood count is bacterial infection the cause?

A high white blood cell count (WBC) is often associated with bacterial infection, but it is not conclusive evidence. Several other conditions can cause an elevated WBC count, including viral infections, fungal infections, autoimmune diseases, allergies, trauma, and certain medications. Therefore, it's important for a healthcare professional to conduct a thorough evaluation, including laboratory tests, physical examination, and medical history, to determine the underlying cause of the high WBC count and provide appropriate treatment.
