Dear Madam, Hi & Welcome. It depends upon the stages of the infection. A person with active shingles can spread the virus when the rash is in the blister-phase. A person is not infectious before the blisters appear. The virus is spread through direct contact with fluid from the rash blisters caused by shingles. Once the rash has developed crusts, the person is no longer contagious. However, the virus that causes shingles, the varicella zoster virus, can be spread from a person with active shingles to another person who has never had chickenpox. Those who had chickenpox during your childhood (like in your case) are unlikely to develop shingles because of the lifelong immunity following the infection during childhood. So, there s nothing to worry about it. Hope this answers your query.
