1E91.2/B02.7 Disseminated zoster



Disseminated zoster is caused by the varicella-zoster virus (VZV), the same virus that causes chickenpox.


Diagnosis of disseminated zoster is made based on the presence of skin lesions of the same type (usually vesicles) in multiple areas of the body. Blood tests may also be performed to confirm the diagnosis.

Differential diagnosis

Differential diagnosis of disseminated zoster includes other viral infections such as herpes simplex, molluscum contagiosum, and acne vulgaris.


Treatment of disseminated zoster includes antiviral medications, such as acyclovir or valacyclovir, and supportive care.


The prognosis of disseminated zoster is generally good with prompt treatment. Most patients will recover fully. However, some may experience complications, such as vision loss, paralysis, or encephalitis.
