Most toddler rash comes out only once, but some babies may have toddler rash twice. ESE is caused by human herpesvirus-6 infection and is mainly seen in infants and young children who are in good condition. The fever may be accompanied by febrile convulsions, swollen lymph nodes behind the ear and occipital area, and mild vomiting, diarrhea and other digestive symptoms. After 3-5 days of fever, the child’s fever subsides and the rash comes out, and the disease is basically cured. The red rash mainly appears on the head, face, neck and torso, but is less common on the extremities, and the rash usually comes out one day and starts to fade the next. It is recommended that your baby go to public places as little as possible during the rash to avoid spreading the virus to other children.
