How is viral fever caused

Patient's question:

Child has a viral fever for 3 days, nausea, and weakness

Doctor's answer:

Viral fever is a fever caused by an inflammatory response due to a viral infection in the body, which requires antiviral medications such as ribavirin. Fever can be treated symptomatically with measures like drinking plenty of water, applying warm compresses, and using fever-reducing patches. Physical cooling methods may not be very effective, and if the temperature exceeds 38.5°C, fever-reducing medications such as ibuprofen or acetaminophen can be taken.
