Herpes Zoster (Shingles):SFAF
a condition characterized by painful
blisters that typically appear in a dermatomal (linear) distribution on
the skin following nerve pathways; blisters generally dry and scab leaving
minor scarring. Shingles is caused by reactivation of a previous infection
with the varicella-zoster virus (VZV) that initially causes chickenpox;
VZV lies dormant in the nerves and reactivates when immune defenses are
weakened. Shingles outbreaks may recur more frequently and VZV may become
disseminated in people with HIV disease. Disseminated herpes zoster resembles
chicken pox, with a rash, fever and possibly pneumonia; herpes zoster
may also lead to ocular and neurological complications.
