Herpes Virus The herpes family of viruses includes 8 different viruses that affect human beings. The viruses are known by numbers as human herpes virus 1 through 8 (HHV1 - HHV8). Human herpes virus 1 Human herpes virus 1 (HHV1) is also known as herpes simplex virus 1 (HSV1). It is typically the cause of cold sores around the mouth. HHV1 can also lead to infection in the genital area causing genital herpes usually through oral-genital contact, such as during oral sex. HHV1 infections are contagious and are usually spread from skin-to-skin contact with an infected person through small breaks in the skin or mucous membrane.

This infection accounts for many of the cases of convulsions associated with fever in infancy (febrile seizures). Human herpes virus 7 Human herpes virus 7 (HHV7) is even more recently observed and is closely related to HHV6. Like other human herpes viruses, HHV6 and HHV7 are so common that most of humankind has been infected at some point, usually early in life. HHV7 can also cause roseola, but it is not clear what other clinical effects that this virus causes. Human herpes virus 8 Human herpes virus 8 (HHV8) was recently discovered in the tumours called Kaposi's Sarcoma (KS). These tumours are found in people with AIDS and are otherwise very rare. KS forms purplish tumours in the skin and other tissues of some people with AIDS. It is very difficult to treat with medication. HHV8 may also cause other cancers, including certain lymphomas (lymph node cancers) associated with AIDS. The fact that these cancers are caused by a virus may explain why they tend to occur in people with AIDS when their immune systems begin to fail. The discovery also provides new hope that specific treatments for these tumours will be developed that target the
