(May 2012). Varicella zoster virus or varicella-zoster virus (VZV) is one of eight herpesviruses known to infect humans and vertebrates. VZV only affects humans, and commonly causes chickenpox in children, teens and young adults and herpes zoster (shingles) in adults and rarely in children.VZV is known by many names, including chickenpox virus, varicella virus, zoster virus, and human herpesvirus type 3 (HHV-3).ZV multiplies in the lungs, and causes a wide variety of symptoms. After the primary infection (chickenpox), the virus goes dormant in the nerves, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia.
âVaricella zoster is one of the most contagious viruses we know,â says Gershon. âItâs transmitted when someone with chicken pox or shingles scratches the lesions, and the virus gets in the air.â Shingles is not quite as infectious as chicken pox, she adds. If youâve had chicken pox or the immunization for chicken pox, you already have varicella zoster in your nervous system.
