About Shingles

What are shingles ?

Herpes zoster, commonly know as shingles and also know as zona is a viral disease characterised by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe. The initial infection with varicella-zoster virus (VZV) causes the acute (short-lived) illness chickenpox which generally occurs in children and young people.

Who gets shingles ?

The disease is primarily seen in the elderly, but occasionally it occurs in younger individuals. It affects both sexes and all races with equal frequency and occurs sporadically throughout the year.

How do you get shingles?

A person must have already had chickenpox in the past to develop shingles. Contact with an infected individual does not cause another person's dormant virus to reactivate. However, the virus from a shingles patient may cause chickenpox in someone who has not had it before.

What are the symptoms of shingles?

The first sign is often a tingling feeling on the skin, itchiness or a stabbing pain. After several days, a rash appears beginning as a band or patch of raised dots on the side of the trunk or face. It then develops into small, fluid-filled blisters which begin to dry out and crust over within a few days. When the rash is at its peak, symptoms can range from mild itching to extreme and intense pain. The rash and pain usually disappear within three to five weeks.

How soon after infection do symptoms appear?

The virus lies dormant in someone who has had chickenpox in the past. It can reactivate many years later.

When and for how long is a person able to spread shingles?

A person exposed to a patient with shingles will not get shingles but may get chickenpox. The virus is present at the site of the rash and is contagious for a week after the appearance of lesions (blisters).

Does past infection make a person immune?

Yes. Most people who have shingles have only one episode with the disease in their lifetime. Those with impaired immune systems (people with AIDS, cancer or leukemia, for example) may suffer repeated attacks.

What are the complications associated with shingles?

Shingles is not usually dangerous to healthy individuals although it can cause great misery during an attack. Anyone with shingles on the upper half of their face, no matter how mild, should seek medical care at once. There is some danger that the virus could cause damage to the eye resulting in blindness. Complications are rare but may include partial facial paralysis (usually temporary), ear damage or encephalitis (inflammation of the brain).

What is the treatment for shingles?

Most cases of shingles resolve on their own without specific treatment. Two medications available for use by physicians in treating immunocompromised patients are vidarabine and acyclovir.

What can be to done prevent the spread of shingles?

Chickenpox must be prevented in order to prevent shingles. A vaccine for chickenpox is now available and it is hoped that immunized individuals will be less likely to develop shingles in later life.
