Human Herpesvirus 6
Human Herpesvirus 6 (HHV-6) is composed of two herpes viruses known as HHV-6A and HHV-6B. Almost all human beings contract the virus as a small child (by the age of two) and like most other herpes viruses, it becomes dormant until later in life. The virus is spread through saliva or possibly genital secretions. In many cases, HHV-6 infections are silent or may appear with a fever.
HHV-6A is rare and typically acquired in adulthood. It has been associated with chronic neurological conditions and is found more frequently in patients with diseases such as chronic fatigue syndrome, multiple sclerosis and rhomboencephalitis. HHV-6B is known to be the cause of the common childhood illness roseola infantum or sixth disease and the symptoms are high temperature followed by a rash just as the fever breaks.
