Essay / Research Paper Abstract

A 6 page overview of the Herpes virus family, of which 8 cause disease in humans. All herpes viruses belong to family Herpesviridae and have in common their ability to establish latency during the first active infection caused by one of the viruses. There are more than 100 distinct herpes viruses that have been identified throughout the world. The paper lists the alpha, beta and gamma herpes viruses and discusses etiology, diagnosis and treatment of cold sores and shingles. Bibliography lists 3 sources.

to family Herpesviridae and have in common their ability to establish latency during the first active infection caused by one of the viruses. There are more than 100 distinct herpes viruses that have been identified throughout the world, eight of which have the ability to cause disease in humans. The purpose here is to examine some of these herpes viruses. Overview The eight herpes viruses that have been identified as causing human disease include: * "Epstein-Barr virus, which causes infectious mononucleosis (also known as mono and glandular fever); * "Varicella zoster, which causes chickenpox and shingles; * "Herpes simplex virus type 1, the cause of cold sores; * "Herpes simplex virus type 2, the most common cause of genital herpes" (Herpesviruses, 2003). Herpes viruses are divided into three classifications: alpha, beta and gamma. The members of each of these subfamilies share characteristics of their own. Herpes viruses in the alpha herpesvirus subfamily exhibit "relatively short reproductive cycle, a variable host range, efficient destruction of infected cells and their ability to establish latent infections primarily in sensory ganglia" (Herpesviruses, 2003). Members of the beta herpesvirus subfamily have longer reproductive cycles and a more narrow host range. In this group, infected "cells often become enlarged. Latency can be maintained in the white cells of the blood, kidneys, secretory glands and other tissues" (Herpesviruses, 2003). The gamma herpesvirus subfamily has a narrow host range as well, and is "restricted to the family or order to which the natural host belongs. This subfamily of viruses is specific for either T or B lymphocytes, and latency is often demonstrated in lymphoid ...
