Shingles (herpes zoster) What is shingles? Shingles is a localized infection due to the varicella-zoster virus, the same virus that causes chickenpox. It occurs only in people who have had chickenpox in the past and represents a reactivation of the dormant varicella virus. Why the virus reactivates in some individuals and not in others is unknown. Who gets shingles? The disease is primarily seen in the elderly, but occasionally occurs in younger individuals. It affects both sexes and all races with equal frequency and occurs sporadically throughout the year. How is shingles spread? 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?
Tingling feeling on Skin 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 chicken pox is under development and it is hoped that immunized individuals will be less likely to develop shingles in later life.
