Should I receive intravenous fluids if I've had a fever for three days due to a viral infection?

Fever usually refers to an elevated body temperature. In general, if a fever caused by a viral infection has lasted for three days, intravenous (IV) therapy may be needed; however, if the condition is mild, IV treatment can sometimes be avoided. If discomfort occurs, it is recommended to seek medical attention promptly. The details are as follows:

Fever due to a viral infection may result from the body's immune response against the virus and typically lasts for a relatively long period. If a fever persists for three days and is accompanied by symptoms such as headache, dizziness, nausea, and runny nose, along with muscle aches, fatigue, and decreased appetite, IV therapy might be necessary. Under a doctor's guidance, medications such as peramivir sodium chloride injection, acyclovir injection, or ribavirin injection may be administered to help relieve symptoms.

If symptoms are mild and the patient is in good spirits despite recurring fever, IV therapy may not be immediately required. Physical cooling methods can be used, and oral medications such as ibuprofen tablets, Siji Anti-Virus Capsules, or acetaminophen tablets may be taken as directed by a physician, which can also aid recovery.

During IV treatment, patients are advised to eat light foods such as millet porridge, corn porridge, or vegetable porridge, and to avoid raw, cold, greasy, or spicy foods. Additionally, increasing fluid intake appropriately can promote metabolism and support recovery.
