Basics

Description

  • Commonly known as shingles
  • Characterized by unilateral eruption of painful vesicles along a single dermatome
  • Disseminates rarely in normal hosts and frequently in immunocompromised hosts
  • Most common in patients with decreased cell-mediated immunity:
    • Older than 50 yr of age
    • Neoplastic diseases
    • Immunosuppressive drugs

Etiology

  • Caused by varicella zoster virus (VZV), a DNA virus in the Herpesviridae family
  • Reactivation of dormant virus in dorsal root ganglia
  • Mostly in individuals who previously had chickenpox and very rarely in vaccinated individuals

Pregnancy Considerations
Zoster in pregnancy is not associated with increased risk of congenital varicella syndrome


Pediatric Considerations
May occur in childhood, most commonly when primary varicella occurred in utero or in the first 6 mo of life
