is caused by the varicella-zoster virus, the same virus that causes
chickenpox. After an attack of chickenpox, the virus lies dormant in
the nerve tissue. As we get older, it is possible for the virus to
reappear in the form of shingles. Shingles is estimated to affect 2 in
every 10 persons in their lifetime. This year, more than 500,000 people
will develop shingles.
