What Are the Causes of Recurrent Shingles?

History

Once a person becomes infected with the varicella-zoster virus, it never fully goes away. Instead, after chickenpox clears up, the virus goes dormant in some nerve cells of the body.

Risk Factors

It is not fully understood exactly why shingles occurs when it does, although the Mayo Clinic reports that risk factors include aging and having a weakened immune system.

Features

After a first outbreak of shingles, the varicella-zoster virus goes dormant again, just as it does after chickenpox. This means that further outbreaks are possible.

Prevention

The shingles vaccine can help reduce the chances of a shingles outbreak, even in people who have already had one outbreak, according to the Centers for Disease Control and Prevention.

Considerations

Although the shingles vaccine has been reported by the CDC to lower the risks of developing shingles, including a recurrence of the condition, it is not 100 percent effective in preventing in shingles outbreak.
