Which conditions are associated with varicella-zoster virus?

Varicella-zoster virus (VZV) is the cause of chickenpox and herpes zoster (also called shingles).

What happens if you have varicella-zoster?

The varicella-zoster virus is very contagious. It can cause two health problems: chickenpox and shingles. When you become infected with the virus for the first time, it causes chickenpox. After having chickenpox, most people become immune to the virus for the rest of their life.

What are three diseases caused by varicella-zoster virus?

Varicella-zoster virus (VZV) causes chickenpox and herpes zoster (shingles). Chickenpox follows initial exposure to the virus and is typically a relatively mild, self-limited childhood illness with a characteristic exanthem, but can become disseminated in immunocompromised children.

What does it mean if your positive for varicella?

A positive VZV IgG result indicates the presence of antibodies to varicella zoster virus. The test cannot distinguish between past infection and current infection though, so a positive result could indicate active infection and not immunity.

How long does varicella immunity last?

Duration of Protection But, live vaccines in general provide long-lasting immunity. Several studies have shown that people vaccinated against varicella had antibodies for at least 10 to 20 years after vaccination.

What causes reactivation of varicella zoster virus?

The primary factors that impact a person’s cellular immunity are age and medical conditions or medications that suppress the immune system. Post-pregnancy and menopausal hormonal fluctuations in women have also been linked to VZV reactivation.

What is the normal range for varicella zoster virus?

0.91-1.09 ISR: Equivocal – Repeat testing in 10-14 days may be helpful. 1.10 ISR or greater: Positive – Significant level of detectable varicella-zoster virus IgM antibody. Indicative of current or recent infection.

Where does varicella zoster virus come from?

Varicella zoster virus (VZV) is the causative agent of chickenpox and shingles. The geographic distribution of VZV clades was taken as evidence that VZV migrated out of Africa with human populations. We show that extant VZV strains most likely originated in Europe and not in Africa.
