Viral fevers in children can be treated with fever-reducing medications if they are above 38.5°C. Common medications are usually ibuprofen and acetaminophen, which have a certain antipyretic effect on viral fever. When the body temperature does not reach 38.5℃, it is usually recommended to take physical cooling methods, such as using warm water on the forehead or wiping the armpits, groin and other parts of the body can achieve the role of temperature control. You can also eat more nutritious foods, such as fruits and proteins, to strengthen your immune system.
