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.
Herpes/Varicella Zoster VirusJAMA The varicella-zoster virus causes chicken pox in children and may reappear in adults as herpes zoster. Also called shingles, herpes zoster consists of very painful blisters on the skin that follow nerve pathways.
