Varicella-Zoster Virus - VZV
Varicella-zoster virus (VZV) is the etiologic agent of chickenpox in children and herpes zoster (shingles) in adults. According to the CDC, clinical diagnosis is challenging because fewer people get varicella and varicella in vaccinated people is often mild and atypical in presentation. Therefore, laboratory confirmation of varicella is becoming increasingly important in routine clinical practice. Antibody testing can be used to assess immunity to VZV, and DFA and PCR can both be used on fluid from lesions for rapid identification of the virus.
