Molecular mechanisms of varicella zoster virus pathogenesis
WEBVaricella zoster virus (VZV) is the causative agent of varicella (chickenpox) and zoster (shingles). Investigating VZV pathogenesis is challenging as VZV is a human-specific virus and infection does not occur, or is highly restricted, in other species.
Laboratory Testing for Varicella-Zoster Virus (VZV)
WEBMay 10, 2024 · PCR is the most useful laboratory test for confirming suspected varicella and herpes zoster. PCR can detect VZV DNA rapidly and sensitively in skin lesions (vesicles, scabs, maculopapular lesions). Specimens for PCR testing. Vesicular lesions or scabs, if present, are the best for sampling.
