3 years and a half fever 39 degrees how to do

Children aged three and a half years old whose temperature reaches 39 ℃ belong to high fever, which is easy to cause febrile convulsions. Suggestion: Parents need to take children to the local regular hospital pediatrics in time to see a doctor. After clarifying the cause, follow the doctor's advice and apply antiviral drugs for treatment. During the treatment period, give children more water to promote the excretion of toxins in the body, which is conducive to recovery.
