This is a layman's understanding of the situation. Shingles occurs in individuals who have already had episodes of chickenpox, sometimes many years prior to the shingles. The virus doesn't leave the system after the course of the original episode of chickenpox. The virus takes up residence in various parts of the nervous system, where it just remains completely harmless for most people. It is not clear what triggers an episode of shingles, but the virus will sometimes work its way down the nerves/neurons to cause an episode of 'shingles'. Shingles itself is not caused (at least directly) by exposure to an airborne virus. Chickenpox, however, can be transmitted as an airborne infection. Possibly, although rarely, an individual may become infected with chickenpox following skin contact with the virus, since it has high concentrations in the liquids in the characteristic body lesions.
No. You only get shingles's if you have had chickenpox. No chickenpox no shingles's.
Shingles is caused by the chickenpox virus. You do not get shingles from someone with shingles; you get chickenpox from someone with shingles. Then when you get older, you will get shingles because you had chickenpox. Or, you might get older and never get chickenpox. In that case, you will thank your mother for having you vaccinated against chickenpox when you were a child.
Chickenpox and shingles are found throughout the world.
Once you get the chicken pox infection, the virus gets hidden in your posterior root ganglion. How does it evades the immune system is poorly understood. It comes out in the form of herpes zoster or shingles, when your immunity lowers down. There is no mutation of the virus.
Shingles and chickenpox can only be transferred by someone who is infected.
First, you can't get shingles at any age unless you have previously had chickenpox. Although your chickenpox illness may have been so mild that you didn't notice, a diagnosis of shingles is proof that you had chickenpox. Second, only those who have never had chickenpox can get chickenpox from shingles. Third, shingles is only contagious through direct contact with wet lesions, and is not likely to be spread through casual contact.
You can't get shingles from someone with chickenpox, whatever your other medical conditions. You only get shingles from reactivation of your own prior infection with chickenpox virus.
No. While you can catch chickenpox, shingles comes from a virus already within you (chickenpox virus) so you can only have shingles if you have previously had chickenpox. I myself had shingles back when I was in the fourth grade but neither my brother nor my sister ever had it.
No, it is not.
No. You can however catch chickenpox from the shingles if you've never had them before. The shingles themselves come from a dormant chickenpox virus in your skin tissue.
No, there is no reason to get chickenpox vaccine if you've had shingles. You should talk with your health care provider about shingles vaccine.
You appear to be confused about the nature of shingles. A positive varicella titer shows that you have had chickenpox in the past, or that you have had the vaccine for chickenpox. You can't get shingles unless you've had chickenpox. If you have had chickenpox, a positive varicella titer is not protective against shingles, and you may need the vaccine. Discuss with your health care provider whether shingles vaccine makes sense for you.
