N: 1. -herpes: late 14c., “any inflammatory, spreading skin condition” (used of shingles, gangrene, etc.), from Latin herpes “a spreading skin eruption,” from Greek herpes, the name for the disease shingles, literally “creeping,” from herpein “to creep, move slowly” (cognate with Latin serpere “to creep;”). The condition was not distinguished into specific diseases until early 19c.
– zoster: kind of seaweed, c. 1600, Latin, from Greek zōstēr “girdle,” originally “warrior’s belt,” from zōnnynai (see zone (n.)). Meaning “shingles” is from 1706; in the literal sense, “a belt or girdle, especially for men,” from 1824.
• Classification System Code: B02.
2. It is an infection that results when varicella-zoster virus reactivates from its latent state in a posterior dorsal root ganglion. Symptoms usually begin with pain along the affected dermatome, followed within 2 to 3 days by a vesicular eruption that is usually diagnostic. Treatment is with antiviral drugs, ideally given within 72 hours after skin lesions appear.
3. Usually, it develops only on one side of the body or face and in a small area rather than all over. The most common place for shingles is a band that goes around one side of your waistline. Some of the symptoms are:
•Burning, tingling, or numbness of the skin
•Feeling sick—chills, fever, upset stomach, or headache
•Fluid-filled blisters
•Skin that is sensitive to touch
•Mild itching to strong pain
Depending on where shingles develops, it could also cause symptoms like hiccups or even loss of vision.
4. Most cases last 3 to 5 weeks. It follows a pattern:
•The first sign is often burning or tingling pain; sometimes, it includes numbness or itching on one side of the body.
•Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear.
•A few days later, the rash will turn into fluid-filled blisters.
•About a week to 10 days after that, the blisters dry up and crust over.
•A couple of weeks later, the scabs clear up.
Most people get it only one time. But, it is possible to have it more than once.
