Can someone become a carrier of the chicken pox virus? i have shingles and my friend wants to come visit. she had chicken pox when she was little, however her little brother at home has not. her mom said if she comes into contact with me she will be a car

In : In short, no. The virus that causes chicken pox and shingles (varicella) can only be spread from direct contact with the infected person either by touching a chicken pox or shingles sore or by the infected person coughing or sneezing on someone who has never had the disease. We do have a vaccine available and it became a required immunization for public school attendance in the early 2000's. Your friend's brother (if he is older than 1) may have been vaccinated and may have immunity to the chicken pox. If not, he should get the vaccine to prevent him from catching chicken pox in the future.

Virus carrier: Yes. If you have active shingles with lesions you could transmit the chickenpox virus to someone else. Once the lesions crust over you aren't contagious. But fluid weeping blisters ARE contagious

Depends: If she comes over & contaminates her hands with debris from the weeping zoster sores she could, in theory transfer that contagion to another for a few hours. (until hands are washed) Otherwise she won't. Shingles does not spread the virus in the air (like chickenpox) so being around you couldn't make her a carrier & those who have had it cannot transport it like they might a strep throat.
