Why Do Hand, Foot, and Mouth Disease Patients Reappear with Rashes?

Question

After four days of intravenous fluid treatment for hand, foot, and mouth disease, the patient has shown improvement, but why do the rashes reappear a few days later?

Answer

Hand, foot, and mouth disease is an infectious disease characterized by rashes appearing on a child’s mouth, hands, feet, and buttocks. After the child receives intravenous fluid treatment, there is some improvement, but the reappearance of rashes may be due to the persistent infection of the virus. It is recommended to conduct urine tests to check for bacterial, viral, or mycoplasma infections and to prescribe medication according to the test results. In severe cases of hand, foot, and mouth disease, it may be necessary to undergo another round of intravenous fluid treatment. Intravenous fluid treatment is harmless to children; on the contrary, if hand, foot, and mouth disease is not properly treated, it may develop into a severe condition, posing great harm to the child’s health. Once parents notice symptoms of hand, foot, and mouth disease in their children, they should seek medical attention promptly and pay attention to their child’s care. It is recommended to provide appropriate nutrition and avoid eating cold foods.
