Screening
Screening for varicella-zoster virus (VZV) immunity
Screening for VZV is important in specific populations. Those with a definite history of varicella or herpes zoster can be considered protected. Pregnant women, solid organ transplant candidates, bone marrow transplant candidates, and other highly immunosuppressed patients should be screened for evidence of VZV immunity.[49][61] Healthcare workers with a negative or uncertain history of varicella or herpes zoster should be serologically tested and be vaccinated if they are found to be seronegative.[20]
