Infantile roseola is a common febrile rash disease in infants and young children, primarily caused by viral infections. The main typical symptoms are high fever, usually around 40 degrees Celsius, followed by a fever lasting three to five days. When the fever subsides, a rash appears simultaneously or afterwards, persisting for 2-3 days before gradually fading. Some children may also experience vomiting, diarrhea, or convulsions during high fever. Therefore, the treatment for infantile roseola is generally symptomatic. During high fever, physical cooling is applied, and appropriate antipyretics are used to prevent febrile convulsions. It is important to ensure adequate hydration and provide easily digestible food. Appropriate heat-clearing and detoxifying traditional Chinese medicines or patent medicines can also be given. If convulsions occur, it is urgent to seek medical attention, and doctors can administer suitable sedatives and antispasmodic medications based on the child's condition. Other symptoms, like vomiting and diarrhea, should be treated with appropriate antidiarrheals or digestive aids as needed, to help alleviate discomfort in the child.
