Are white blood cell counts elevated in influenza A and influenza B?

The phenomenon of elevated white blood cells in influenza A and B, known as increased lymphocyte count, is usually caused by the body's response to a viral or bacterial infection. Influenza A and B are common viral infectious diseases and are among the frequent causes of elevated lymphocyte levels. However, increased lymphocytes may also result from other viral or bacterial infections, such as bronchitis or tonsillitis. The normal reference range for lymphocytes is 1.0–4.0×10⁹/L. In certain cases, lymphocyte counts may exceed this range, with upper limits typically reaching 5.0–8.0×10⁹/L. Therefore, when white blood cell counts in influenza A or B exceed this range, prompt and effective treatment should be administered to prevent the development of sepsis. Treatment options include intravenous fluid therapy and medication. Fluid infusion helps accelerate the recovery of the body's immunity and commonly involves solutions such as sodium chloride and glucose. Medication may include antiviral drugs and antibiotics to suppress viral replication and reduce pathogenic substances, thereby alleviating symptoms. Additionally, patients should actively cooperate with treatment, ensure adequate rest, drink plenty of water, and avoid consuming greasy foods.
