"...a central nervous system disease marked by muscle-wasting, weakness and, in severe cases, a spastic walk, that Japanese and American scientists had recently linked to the first human retrovirus, human T-cell lymphotrophic virus, type 1.

"Recently, scientists at the Wistar Institute, in Philadelphia, reported a link between a specific virus and chronic fatigue. The virus - a retrovirus - was discovered in several small groups of patients suffering from chronic fatigue, including children in an upstate New York town where an epidemic occurred. The virus was detected through extremely sophisticated laboratory tests. Though the discovery does not prove that chronic fatigue is caused by a single specific virus, it supports the increasingly popular theory that many of our chronic diseases may implicate viruses."

"National Cancer Institute researcher Dr. Robert C. Gallo and his colleagues made an astonishing assertion in the Nature study: They reported that a virus found to be actively growing in both AIDS and Chronic Fatigue Syndrome patients, Human Herpes Virus 6 (HHV-6), infects and kills natural killer cells. Moreover, according to the report from the Gallo laboratory, HHV-6 is the only virus known to be able to do that."
"And also like HHV-6, HHV-7 is quite similar to cytomegalovirus (CMV), which can cause blindness and other serious illnesses in AIDS patients. However, HHV-7 is different enough from both HHV-6 and CMV to be declared by Dr. Gallo's research team to be an entirely new human virus.
"An important question not posed by these investigators is: Where are these "new" viruses, found to be infecting both AIDS and CFS patients, coming from?"

"To his amazement, the electron microscope results indicated that the culture was infected with an HTLV-like retrovirus. The virus was budding from cells in the co-culture."

"I personally favor the idea that CFIDS is caused by a specific and still-unidentified virus that defies the immune system. Research now points in that direction, to a virus of the retrovirus family. A promising candidate has shown up in patients with CFIDS. Only time will tell if this virus is the actual culprit." - page 68
