Blood counts in patients with bacterial infections often show an increased white blood cell count, an increased percentage of neutrophils, and a decreased percentage of lymphocytes. Elevated hemoglobin can occur due to blood concentration. Anti-inflammatory treatment with antibiotics is recommended. With effective drug therapy, the patient’s blood count and neutrophil percentage will return to normal, and the hemoglobin will also return to normal. During the period of bacterial infection, patients are advised to take more rest, drink more water, avoid smoking and alcohol, and avoid overexertion and cold to prevent re-infection with bacteria. It is important to lead a regular life and strengthen exercise to improve the body’s own resistance.
