The symptoms of chickenpox in young children usually start with fever and poor circulation at the beginning. The rash first appears on the trunk and then spreads to the head, face and extremities. The rash appears as maculopapular rash, blistering rash, and pustular rash, and usually appears on the day of fever or one day after fever. Most children have mild clinical symptoms, so they should rest and pay attention to skin cleanliness and not scratching. Most of the children will have significant improvement in clinical symptoms after the above treatment. A small number of immunocompromised patients may develop severe chickenpox, and these patients need to be alerted and hospitalization is generally recommended.
