Varicella Zoster Virus (VZV)
Varicella-Zoster Virus (VZV) VZV is a DNA virus and is a member of the herpesvirus group. Like other herpesviruses, VZV persists in the body as a latent infection after the primary (first) infection; VZV persists in sensory nerve ganglia. Primary infection with VZV results in varicella.
B01 - Varicella [chickenpox].
The presence of detectable IgG-class antibodies indicates prior exposure to the varicella-zoster virus (VZV) through infection or immunization. Individuals testing positive are considered immune to varicella-zoster.
The minimum potency of zoster vaccine is at least 14 times the potency of varicella vaccine (Varivax®), which contains a minimum of 1,350 PFU, and is similar in potency to the varicella zoster virus content of measles-mumps-rubella-varicella vaccine (ProQuad®).
Varicella-zoster virus (VZV) (subfamily Alphaherpesvirinae, genus Varicellovirus, species Human herpesvirus 3) is the causative agent of chickenpox and shingles, and is one of eight herpesviruses that have humans as the natural host.
Shingles is caused by varicella zoster virus (VZV), the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays dormant (inactive) in their body. The virus can reactivate later, causing shingles. Most people who develop shingles have only one episode during their lifetime.
Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). It can cause an itchy, blister-like rash. The rash first appears on the chest, back, and face, and then spreads over the entire body, causing between 250 and 500 itchy blisters.
A positive IgG ELISA result indicates that a person has antibodies to VZV either from past varicella disease or vaccination. This test cannot distinguish whether the antibodies were from a past episode of varicella or vaccination.
