It is best not to bathe during chicken pox because there are various kinds of rashes on the body during chicken pox, including herpes, broken herpes, and freshly formed blood scabs. The scabs rub off very easily in the shower, and when they do, there is fresh, unhealed flesh and blood, which may delay healing and even lead to scarring or keloid scars. The herpes is likely to rub off, and the broken herpes is likely to be infected by bacteria due to the bath water. If the rash does not scab over and rub off and there is no secondary bacterial infection, it will not leave a scar after the chicken pox heals, but if the bath causes complications, the chicken pox may leave a scar. Therefore, you should not take a bath during the period of chicken pox, but only after the rash of chicken pox has scabbed over and fallen off.
