Shingles
Moderate
Shingles is a painful skin condition caused by reactivation of the varicella-zoster virus, the same virus that causes chickenpox. After chickenpox, the virus remains inactive in nerve tissue and can reactivate years later. Shingles usually produces pain, burning, tingling, or increased sensitivity followed by a localized blistering rash. The rash commonly occurs on one side of the body or face. Symptoms usually resolve over several weeks, although nerve pain can persist after the skin has healed.

When to Seek Medical Attention
Shingles should be medically assessed, particularly when the rash is extensive, severe, recurrent, or involves the face or eye. Seek prompt care for a rash near the eye, ear, or face, severe pain, or signs of infection. Emergency assessment is appropriate for vision loss, severe neurological symptoms, facial weakness, confusion, or rapidly worsening illness.

Causes 1
Shingles occurs when dormant varicella-zoster virus becomes active again within a sensory nerve. The exact reason for reactivation is not always known. The immune system normally keeps the virus under control, and reduced immune function can make reactivation more likely. After reactivation, the virus travels along a nerve toward the skin and produces the characteristic localized pain and rash. Previous chickenpox infection is required for the virus to remain in the body.
Infection
Risk Factors
The main risk factor is previous infection with varicella-zoster virus. Risk increases substantially with advancing age because immune control of the virus may weaken over time. People with weakened immune systems because of certain illnesses or treatments also have greater risk. Severe physical or psychological stress may be associated with reactivation in some individuals. Shingles can occur in people without an obvious risk factor, so absence of these factors does not eliminate the possibility.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Shingles is usually diagnosed from the characteristic pattern of localized pain followed by a one-sided blistering rash. A physical examination is generally sufficient when the presentation is typical. Laboratory testing may be considered when the diagnosis is uncertain, the rash is atypical, or the affected person has unusual symptoms. A sample from a blister can be tested for varicella-zoster virus. Eye, ear, neurological, or widespread involvement requires particularly careful clinical assessment.
Prevention
Key Prevention Tips
Vaccination against varicella-zoster virus can reduce the risk of chickenpox and later shingles, while shingles vaccination can reduce the risk of shingles and its complications in eligible people
Recommendations vary according to age and health status
Maintaining general health and appropriate management of conditions that weaken immunity may also be beneficial
People with an active rash should avoid direct contact with individuals who are particularly vulnerable to varicella infection until lesions have crusted
Prevention Guidance
Vaccination against varicella-zoster virus can reduce the risk of chickenpox and later shingles, while shingles vaccination can reduce the risk of shingles and its complications in eligible people. Recommendations vary according to age and health status. Maintaining general health and appropriate management of conditions that weaken immunity may also be beneficial. People with an active rash should avoid direct contact with individuals who are particularly vulnerable to varicella infection until lesions have crusted.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
