The term embracesprimarily two distinct disorders, herpes virus simplex and herpes zoster, both typefacedby viruses. Together, these "herpes" viruses are estimated to cause more charitableillnesses than any separate group of viruses.     Two types of herpes simplex are known. The first causes cold sores orfever blisters, which is an eruption of blisters that often occurs during the division of or after one of a variety of diseases that in conclusion cause fever(most commonly average colds, the flu, and pneumonia). The blisters usuallyappear around the let loose and on the lips (herpes labialis), about the nose, face,and ears, and in the mouth and pharynx. The causative virus has been shown to bepresent in the cell bodies of the facial nerve in persons who do not haveblister s. It is this reservoir of latent virus that is the source of repeatattacks.

When a baby is innate(p) to a woman who has active genital herpeslesions, the infant is at high risk of contracting an infection that is oftenfatal, so these women usually have their babies delivered by a cesarian section.Primary cases of genital herpes can be treated by a drug called acyclovir, whichwas clear in 1982 and in another form, that is to be taken orally quite an thanused in an ointment form, in 1984. It also has been proving useful againstrepeated attacks.     The virus can also invade the central nervous system, or CNS, especiallyin people who are weakened by other diseases, such as cancer, causing a severecase of encephalitis.
