Herpes-Simplex Type 2     Herpes is a name that is used to describe several types of skineruptions that are characterized by variantation of blisters. The term embracesprimarily two distinct disorders, herpes unidirectional and herpes zoster, both causedby viruses. Together, these "herpes" viruses are estimated to cause more than humanillnesses than any other group of viruses.     Two types of herpes simplex are known. The first causes cold sores orfever blisters, which is an eruption of blisters that practically occurs during thecourse of or after one of a variety of diseases that last cause fever(most commonly average colds, the flu, and pneumonia). The blisters usuallyappear more or less the mouth 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 haveblisters. It is this r eservoir of latent virus that is the cum of repeatedattacks. Except for lotions to relieve pain, itching, or inflammation, noestablished treatmemt has truly been developed.     The second type of the herpes simplex virus, however, is the usual causeof venereal herpes. Herpes infections of the venereal area have becomeincreasingly common, freeing along with a rise in general of many sexuallytransmitted diseases. Sometimes accompanied by headache and fever, the conditionusually begins with a mild itching, followed by the development of clusters ofblisters that break and crust to form scabs that eventually dry up. The processmay last one to tether weeks. In many object lessons new clusters of blisters appear asothers heal. When a queer is born to a woman who has active genital herpeslesions, the sister 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 gen ital herpes can be treated by a medicine called acyclovir, whichwas approved in 1982 and in another form, that is to be taken viva voce rather thanused in an ointment form, in 1984. It also has been proving serviceable againstrecurrent attacks.     The virus can also invade the central sickish system, or CNS, especiallyin people who are weakened by other diseases, such as cancer, causing a severecase of encephalitis.
