Understand and Treat Shingles
This site gives information on the causes, treatment, prognosis and latest research on Herpes Zoster. Shingles or herpes zoster is a painful and sometimes debilitating viral disease that afflicts nearly one million Americans annually. The Herpes Zoster virus can remain in the body for many years, often from the time of a childhood episode of the chickenpox. As people get older, their immune system naturally weakens to some germs, such as herpes zoster. The virus normally lays dormant in nerve cells, but in some people the virus reactivates years, or even decades, later and causes herpes zoster. Anyone who has had the chickenpox infection or vaccine can get the herpes zoster virus that causes shingles. About 20 percent of people who have had chickenpox will develop herpes zoster. Patients with herpes zoster are contagious to those who lack immunity, but less so than patients with varicella. Unlike herpes simplex I, the varicella-zoster virus (VZV) does not usually flare up more than once in adults with normally functioning immune systems. Shingles (herpes zoster) most commonly occurs in older adults. The medical term for shingles is acute herpes zoster.
