Patients with viral fever that does not go away are at risk. The presence of a fever that does not go away is evidence of a serious viral infection, and if it is not treated promptly and effectively, it may lead to complications, including pneumonia, meningitis and myocarditis, which are more common in clinical practice. When a patient develops a comorbidity, it can seriously endanger the patient’s health. Therefore, when a patient has a viral fever that does not subside, active and effective antiviral measures should be taken, as well as cooling measures for treatment. Patients are advised to take intravenous ribavirin, Qingkailing injection and other antiviral drugs in a timely manner. It can also be combined with oral administration of Chinese medicines such as Lianhua Qing Wen capsule and Banlangen granules to clear the heat and detoxify the toxin, and patients should also take antipyretic drugs such as ibuprofen granules to carry out cooling treatment and relieve the discomfort caused by fever.
