Question
What are the types of hand, foot, and mouth disease infections?
Answer
Hand, foot, and mouth disease primarily affects children under 10 years old. Typical symptoms include the recurrence of ulcers in the oral mucosa, accompanied by symptoms such as coughing, runny nose, and loss of appetite. Some cases may only present as rashes or herpangina. Most cases recover within a week. There are numerous types of hand, foot, and mouth disease viruses, and transmission is not always obvious. In some cases, the disease may manifest only as macules or papules. Severe cases are rare, with rapid progression of symptoms. Immunosuppressed children may develop symptoms such as meningitis, encephalitis, and pulmonary edema within 1 to 5 days of onset. Once the condition worsens, it is extremely difficult for children with strong resistance to the hand, foot, and mouth disease virus to recover, with low survival rates.
