an exposure to an infectious disease like chicken pox does not make you a "carrier". you actually have to have the disease or at least staged to get the disease (at the end of an incubation period) to be able to transmit it to others. if you had chicken pox (varicella) as a child you are most likely immune but any new exposure could cause a reactivation of this latent herpes virus and cause you to get shingles (herpes zoster). have you had the shingles vaccine? because of your exposure to children this may be something for you to discuss with your medical provider.
if i had chicken pox as a child (i am 57) but i am exposed to it from a child can i spread the virus to others? . i work at a dance school and the last thing i want to do is give the studentd chicken pox.
