[|AI|]  Hello, Welcome to Chat Doctor, Chickenpox is a highly communicable 1-2 days before the appearance of rash and 4-5 days thereafter. After which virus tends to die out and looses the capacity to transmit disease to normal individuals. As your 4-year-old son has just come out in a rash which looks like rashes of chicken pox, he has all the chance of transmitting the disease to other health individuals including the adults. The scabbing usually begins 4-7 days after the rash and completed by 30 days. During the scabbing period your son will be sterile and will not transmit disease to others. Thank you.
