Question
After the baby’s hand, foot, and mouth disease has healed, the blisters on the feet have already healed, but new blisters have appeared on the hands and face. Why is this happening?
Answer
Hand, foot, and mouth disease is a self-limiting illness caused by the Coxsackie virus, characterized by blisters appearing on the hands, feet, and mouth, primarily affecting infants and young children. The disease is self-limiting and usually does not require special treatment; symptomatic therapy and enhanced care are sufficient. The mouth can be cleaned with a weak saltwater solution or wiped to prevent secondary infections; skin damage on the limbs and trunk can be treated with calamine lotion to reduce swelling and pain, also to prevent secondary infections. Antiviral medications such as Viruxol can be taken if necessary.
