Can herpes zoster cause other kinds of herpes?

Although they have similar names, herpes zoster is not related to herpes simplex. Herpes simplex is caused by a different virus, and its primary symptoms are watery blisters around the mouth (cold sores), lips or genitals. Herpes zoster does not cause herpes simplex. Herpes simplex can lead to its own eye problem, herpes keratitis.
