Causes of shingles rash

Shingles rash occurs from a virus that causes chickenpox. When the virus that is responsible in causing chickenpox attacks the body again, you suffer shingles and not chickenpox. If you suffered chickenpox, the virus is still in your body but in a dormant state.

In some people, this virus may wake up and attack the body while in others it never starts up again. When you suffer chickenpox, the virus, which causes the condition, goes into a dormant state in your nerve roots. Whereas for some people, it remains there for the rest of life, for other, it wakes up and attacks the body.

However, when it re-attacks the body for a second time, it does not cause chickenpox but shingles. People with weaker immune systems due to aging, stress or taking of certain medication can suffer this condition. Some medication can trigger the virus to become alert and start up again causing a painful rash.

It is not clear why the virus restarts against but what is known is that when it restarts, it can only cause shingles and not chickenpox.
