Is shingles contagious?
Is shingles contagious? Yes and no. Shingles is not transmittable to persons who have already had the chicken pox virus. However, people with shingles are contagious to persons who have not had chickenpox. Shingles is caused by the chickenpox virus which has been dormant in your body ever since you had chickenpox. So, you get shingles from your own chickenpox virus, not from someone else.
People with shingles can transmit the virus only if the blisters have broken and the virus is transmitted when skin-to-skin contact with broken blisters occurs. If you have shingles, avoid contact with infants, children, pregnant women, and adults who have never had chickenpox until your blisters are completely dry.
What causes shingles? Varicella zoster virus, the same virus that causes chicken pox, causes shingles. Also called herpes zoster, the virus is in the herpes family. Shingles is not a new infection; rather, it is a second outbreak of the chicken pox virus. Some of the virus germs that cause chicken pox stay in the body, remaining inactive in the nerve cells near the spine for many years. Then the herpes zoster virus suddenly wakes up from the dormant state and grows. Once active, the germs travel along the nerve paths to the skin, leaving a path of destruction along the nerves in which they travel. The result is the pain and rash of shingles.
Unfortunately, it isn't yet known exactly what causes the varicella zoster virus to become active again. An important factor, though, is the immune system, which helps keep viruses at bay. Shingles tends to appear when your immune system is weakened. For example, the chances of getting shingles are higher as we get older. But other things can also weaken, or suppress, the immune system's ability to fight infection, such as HIV, anticancer and transplant drugs, stress, and depression.
