What is the reason for the recurrence of red rashes on the body after getting hand, foot, and mouth disease?

Patient's question:

My daughter was about 2 a.m. today when she started having a low fever, wasn't eating milk, and had red rashes on her hands and feet. During the day, we took her to the hospital to see a doctor and she took medication. By noon, new red rashes appeared on her hips, buttocks, and back, with her inner thighs turning bright red. By the evening, numerous blisters had developed around her inner thighs and private area. What could be the cause?

Doctor's answer:

Hand, foot, and mouth disease refers to the recurrence of blisters on the hands, feet, buttocks, and inside of the mouth, often accompanied by fever. It is most commonly caused by viral infections, although a small number of severe cases may be due to bacterial infections. To diagnose hand, foot, and mouth disease, a urine test is required to check for bacterial, viral, or mycoplasma infections. Based on the test results, symptomatic treatment should be administered. If the urine test indicates severe contagiousness, hospitalization and intravenous fluid treatment may be necessary. A light diet, consisting of fine and easily digestible foods, is recommended.
Children threatened by hand, foot, and mouth disease should be taken to the doctor immediately for treatment to prevent the misuse of over-the-counter medications. Proper medication is essential. For parents, closely monitoring changes in their child's symptoms is crucial, as timely treatment can help recover from the disease more effectively.
