Chicken pox is one of the most common infectious problems in childhood, although it is decreasing as most children are now vaccinated. Your pediatrician
would be able to discuss this issue with you in great detail. Chicken pox is a very contagious viral infection that is caused by the varicella virus. The infection can be spread both through the air (by coughing) as well as by contact with the fluid inside the chicken pox lesions. Usually people with chicken pox are infectious for several days already before they know they have chicken pox (before the rash appears) by coughing. After the rash appears, the blisters are highly contagious until they have completely scabbed over. Generally the recommendation is that the child can return to school when all of the chicken pox lesions have scabs on them. It is not necessary to wait until the spots have entirely healed. In addition to passing the infection to other children, chicken pox can be very dangerous for people with immune conditions, serious illness
like cancer, or pregnant women, who should all avoid exposure to cases of chicken pox. As always the diagnosis and the management of your child's specific condition will require a physical examination by their pediatrician. Scheduling an office visit is highly recommended.
