About Varicella-Zoster Virus (VZV)
The varicella-zoster virus causes chickenpox, a contagious disease marked by itchy rash and fever. Once infected, the virus can remain dormant in the body and reactivate later in life as shingles (herpes zoster).
Knowing your immune status helps protect you and those around you—especially infants, pregnant individuals, and people with weakened immune systems.
