Typically the rash first appears on the head and back, spreading over the next 3-4 days to cover most body surfaces. The child is infectious until every bump has crusted over, which takes 7-10 days from when the rash first appeared. Sores may appear on the mucous membranes as well, which means that the mouth, throat, and genital areas can become involved. When these areas are involved the child may have additional discomforts. Along with rash, there usually is fever, mild headache, decreased appetite, and the child will be less active than usual.
Some children have mild cases of chickenpox and feel quite well during the course of the infection.
Baths can be taken several times a day if they are helpful. Often a medication to decrease itching such as Benadryl or Atarax will be recommended. Both medications are very effective, especially at bedtime when itching is most bothersome. Both medications can cause drowsiness. If neither Benadryl nor Atarax was prescribed and bathing has not relieved itching, then contact your healthcare provider.
