What is oral ulcer fever?

Suggestion: Family members first need to use a thermometer to determine the child's temperature. When the temperature is below 38.5 degrees Celsius, physical methods such as ice compress and antipyretic paste can be used to cool down. Children with a temperature above 38.5 degrees Celsius need oral antipyretic drugs to cool down. Children usually need to eat more fruits and vegetables, and intake sufficient vitamins to promote the disappearance of oral ulcers. If the child is also accompanied by infection, they need to actively use anti-infective drugs.
