Acute bronchitis can cause fever. In such cases, there is no need for excessive worry, as fever is a common symptom of acute bronchitis. It is advised to actively manage the fever. If the body temperature exceeds 38.5°C, take antipyretic medication; otherwise, use physical methods to reduce fever, such as wiping the patient's limbs and back with a warm towel to cool down; you can also apply fever cooling patches, or take some antipyretic medication to treat and alleviate symptoms; applying a cold towel to the forehead can also achieve the purpose of cooling. Additionally, let the patient rest more, avoid excessive fatigue, drink more water to enhance excretion, and improve their own resistance. At the same time, follow a doctor’s guidance to actively treat the symptoms. As the onset of acute bronchitis is often sudden, it is advised to address the symptoms appropriately.
