Hand, foot, and mouth disease with a fever of 40 degrees Celsius is dangerous?

Patient's question:

Blisters on hands and mouth, fever of 41 degrees

Doctor's answer:

The symptoms of hand, foot, and mouth disease are a set of clinical manifestations caused by a viral infection, primarily characterized by fever, blisters on the mouth, hands, and feet. Generally, it can be recovered within 7 days, so there is no need to worry. When there is fever and other clinical symptoms, symptomatic treatment can be applied.
There are multiple causes of hand, foot, and mouth disease. If a child is diagnosed with it, parents need to cooperate with the doctor for timely treatment, including gastrointestinal decompression, and develop good hygiene habits. Parents should pay attention not to develop picky eating habits in children and ensure a balanced diet.
