Can children who have had hand, foot, and mouth disease get infected again?

Patient's question:

My child had hand, foot, and mouth disease six months ago. They were hospitalized for treatment for over a week and have now fully recovered. However, a few days ago, my child played with a child who is currently suffering from hand, foot, and mouth disease. In this situation

Doctor's answer:

Since there are many types of enteroviruses that cause hand, foot, and mouth disease, it makes children particularly susceptible to the illness. Additionally, patients who have previously suffered from osteosarcoma are also not immune to recurrence and are likely to be affected again. Children under the age of 5 are especially prone to contracting the disease during certain periods. Mild cases can be cured within 7 to 10 days with proper medication and daily home care. Wishing all patients a speedy recovery!
