The rash usually resolves in 3-5 days, with individual differences in the time to complete resolution. It is a common acute illness in young children, with self-limiting symptoms such as fever and rash, and is characterized by a “fever-relief rash”. Usually the child’s fever lasts 3-5 days and then the body temperature suddenly drops. The rash usually comes out in about 1-2 days, and the rash starts to fade gradually the day after it appears, and basically fades completely in 3-5 days. Young children should pay attention during the rash and avoid eating seafood or spicy and stimulating foods. When the rash is large, you can apply topical Furamyl lotion; when itching is obvious, you can take oral anti-itch medication as prescribed by the doctor.
