What is the shingles virus?

The varicella zoster virus, also known as the shingles virus, is the same virus that causes the chickenpox.

If you have had chickenpox, and that’s over 90% of adults, your immune system may have been able to keep the virus under control.

However, as we age our immune system naturally weakens. As a result, the shingles virus may reactivate, increasing the risk of developing shingles.
