High white blood cell counts can happen for a lot of reasons: infection, inflammation, allergies, taking steroids (like prednisone), and strong emotional or physical stress. Did the doctor do a differential to see which types of white blood cells are high? Knowing that can help determine why you have a high white count. As for how often "normal" people have a high white cell count, I don't know.
