(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.
However, Varicella is the name of the virus that causes the condition called chicken pox. It also causes a similar condition called shingles. Varicella zoster comes from the same family of viruses like herpes. They all exhibit similar patterns of infection. The scientific name of chicken pox is chicken pox only. There has never been a scientific name for the disease as such. Chicken pox has been around for more than a century. It was more prevalent in the west and as the English started traveling, the disease spread into almost all countries in the world.
