Shingles is a painful rash that results when the chicken pox virus or varicella-zoster, reactivates inside your body. After getting chicken pox — at whatever age — the virus lies dormant in the dorsal root ganglia, or nerve roots, in the spine rather than being destroyed in your body. As you age, declining immunity may allow the varicella virus to reawaken, and travel up the nerve to the skin, resulting in a blistering rash and other health complications. You might be wondering: is this potentially serious disease contagious, and if so, when can you catch it from someone else?
Answer: According to the US National Institutes of Health (NIH), shingles is not contagious, so you can't catch it from someone who has an active shingles infection. However, since the shingles rash does contain the varicella-zoster virus, you can catch chicken pox from someone with shingles, if you've never had chicken pox or been vaccinated against it.
The US Centers for Disease Control and Prevention (CDC) recommend covering the shingles rash with clothes or dressings, in order to reduce the risk of passing chicken pox to someone else. In addition, avoid contact with anyone susceptible to chicken pox, such as pregnant women, premature infants, and people with a compromised immune system.
