How many days does a viral fever usually last in adults?

Fever usually refers to an elevated body temperature. In adults, viral fever typically takes about 3 to 5 days to resolve. However, the exact recovery time varies from person to person, depending on the severity of the illness and individual physical condition. Under a doctor's guidance, antiviral medications such as oseltamivir or ribavirin granules can be used to treat viral fever, which may help speed up recovery.
