What should I do if I have hand, foot, and mouth disease with vomiting and fever?

Patient's question:

My baby is three years old this year. Today, I had a thorough blood test, and the only abnormal result was that the hypersensitive C-reactive protein was 8.48, with a reference range of 0-5 (slightly elevated). Additionally, there are oral ulcers, and he had a fever for the first three days, which has now subsided. The doctor at the hospital said it was hand, foot, and mouth disease with mild encephalitis. What do you think of this diagnosis? Thank you!
Regarding my local hospital's diagnosis: what do you think?

Doctor's answer:

Hand, foot, and mouth disease is a common infectious illness caused by various different enteroviruses, characterized by the recurrence of blisters on the hands, feet, and mouth. Infants and young children are primarily affected, with children under the age of 4 being particularly susceptible to this disease. The condition is usually mild and short-lived. Simple oral herpes often appears in the pharynx and is considered to be herpangina, which is caused by Coxsackie virus infection. Symptoms may include fever, sore throat, and drooling. The diagnosis of encephalitis primarily involves testing the cerebrospinal fluid. Hand, foot, and mouth disease can cause significant harm to children. If a mother notices symptoms in her child, she should take the child to a regular hospital for diagnosis immediately. At the same time, attention should be paid to the child's care. It is recommended to follow a light diet.
