Why Does Hand, Foot, and Mouth Disease Come with Fever?

Question

A one-year-old three-month-old boy has been experiencing a slight fever since yesterday and discovered red bumps on his buttocks, which were diagnosed as hand, foot, and mouth disease. However, today he noticed that the red bumps on his buttocks have expanded into larger patches, and there are also red spots on his tongue. Is this still a symptom of hand, foot, and mouth disease? Why does it come with fever?

Answer

The characteristics of hand, foot, and mouth disease include fever, oral ulcers, and rashes or blisters on the hands, feet, buttocks, and other parts. Fever is the body’s natural response to fighting viral infections. Rashes and blisters usually fade gradually within a week. Treatment should focus on isolation to prevent cross-infection and proper oral care along with symptom relief. The infection process may be prolonged, so it is recommended to continue treatment observations and pay attention to the child’s mental state. If there are no complications and the child is in good spirits, there is no need to excessively use antiviral drugs or antibiotics; continuous observation is sufficient. If the child has poor sleep quality, it should be actively checked
