Shingles: The Disease, the Vaccine, and the Role of Nurses in Vaccination Conversations
Shingles: The Disease
Shingles, also known as herpes zoster, is a painful viral condition caused by the reactivation of the varicella-zoster virus (VZV), the same virus responsible for chickenpox. While anyone with a history of chickenpox is at risk of developing shingles, the likelihood increases with age and in those with weakened immune systems. The disease can lead to significant morbidity, including postherpetic neuralgia (PHN), a debilitating complication characterized by persistent nerve pain. Fortunately, effective vaccination exists, and nurses play a critical role in raising awareness, educating patients, and promoting vaccine acceptance.
Shingles occurs when the varicella-zoster virus, which remains dormant in the dorsal root ganglia after a person recovers from chickenpox, reactivates. This reactivation typically happens decades later, often due to age-related decline in cell-mediated immunity or immunosuppressive conditions. Upon reactivation, the virus travels along sensory nerves to the skin, causing a painful, blistering rash.
- Prodromal phase: Patients often experience tingling, itching, or localized pain in a dermatomal distribution (typically on one side of the body, not crossing the midline), lasting several days before the rash appears.
- Rash phase: A painful vesicular rash develops, usually resolving in 2 to 4 weeks. Common sites include the torso, face, or […]
