What should I do if a three-year-old child has cough and fever?

When a three-year-old child has cough and fever, parents can take the following measures: 1. Fever increases fluid loss in the body; drinking an appropriate amount of warm water helps replenish fluids and promotes metabolism. 2. Eat more fresh fruits and vegetables to supplement vitamins, which also aids recovery. 3. If body temperature does not exceed 38.5°C, use a warm, damp towel to wipe areas such as the forehead and armpits. 4. If body temperature exceeds 38.5°C or if there is a history of febrile seizures, antipyretic medications such as ibuprofen may be taken as directed by a physician. If symptoms persist or worsen, prompt medical attention is recommended.
