Herpes is the medical name for a group of similar viruses. This group includes the varicella-zoster virus, which causes chicken pox as well as shingles; the Epstein-Barr virus, which causes infectious mononucleosis (mono); cytomegalovirus (CMV), which is responsible for infections that usually afflict newborns and people with defective immune systems; and the herpes simplex virus (HSV), which causes genital and oral infections.
