You can blow on a fan with influenza A, but it is not recommended to avoid catching a cold and aggravating cold symptoms. Although the cause of influenza A is influenza A virus infection, resulting in a series of cold symptoms. During the course of the illness, the patient’s own immunity is relatively low, and blowing on the fan at this time may result in catching a cold, exacerbating the symptoms of the cold, which is not conducive to the recovery of the condition. If fever occurs during the course of influenza A, combining antipyretic medications such as acetaminophen can be used to control body temperature, while drinking more water to speed up metabolism. It is a more scientific response to be able to effectively lower body temperature and improve conscious fever symptoms. Patients with influenza A can also take the neuraminidase inhibitors oseltamivir and zanamivir for antiviral treatment under the guidance of a physician. Therefore, it is recommended that patients with influenza A try not to blow the fan, and promptly consult a doctor, under the guidance of the doctor for scientific treatment.
