The virus responsible for chicken pox is known as varicella zoster virus, which is classified as a member of the herpes virus family. This virus is specifically the causative agent of both chicken pox (varicella) and shingles (herpes zoster). When an individual is infected with varicella zoster virus, they typically experience an itchy rash along with fever, fatigue, and other flu-like symptoms, which are characteristic of chicken pox.

While human herpes virus 3 refers to the same virus as varicella zoster virus, the more precise terminology widely accepted in medical literature and practice is "varicella zoster virus." This distinction is important for clarity in understanding virology and the specific diseases associated with different viruses. The other viruses listed, such as HIV and influenza virus, are responsible for completely different diseases and do not have any relation to chicken pox.
