Clinical Significance
Varicella-Zoster Virus (VZV) is a member of the Herpesviridae family that causes varicella (chickenpox) as primary infection and herpes zoster (shingles) upon reactivation. Chickenpox is a childhood infection presented as generalized vesicular rash on the dermis in normal children, usually before 10 years of age. After the primary infection, the virus persists in latent form in the dorsal ganglion and may retrograde in elderly or immunocompromised host to cause shingles that presents as a unilateral vesicular eruption, generally in a dermatomal distribution. VZV DNA in skin lesions, cerebrospinal fluid (CSF) and specimens from respiratory tract specimens permits rapid and sensitive patient testing and usually indicates active, not latent, infection. A negative result does not exclude the possibility of VZV infection. This assay is only to be used for patients with a clinical history and symptoms consistent with VZV infection, and must be interpreted in the context of the clinical picture. This test is not used to screen asymptomatic patients.
