Can I still get infected with hand, foot, and mouth disease after recovering from it?

Patient's question:

Patient Age: Two years old, with hand, foot, and mouth rash for one week
Treatment history and effectiveness: Has the hand, foot, and mouth disease been treated and cured? Do I have immunity now? Will I still be infected in the future?

Doctor's answer:

Hello, hand, foot, and mouth disease refers to the appearance of blisters on the hands, feet, buttocks, and inside the mouth. It is usually accompanied by fever, and the most common cause is a viral infection. In some severe cases, bacterial infections may also occur. If you have hand, foot, and mouth disease, blood tests are needed to check for bacterial, viral, or mycoplasma infections. Treatment should be based on the blood test results. If the test indicates a severe infection, hospitalization may be required for intravenous fluid therapy. Eat a light diet and consume soft, easily digestible foods. Oral blisters can be treated with a children's spray.
