In 1984, there was an outbreak of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) (then thought to be Chronic Epstein-Barr Virus) at Incline Village, Nevada, United States.[1] Incline Village is a small town on the north shore of Lake Tahoe.

Chronic fatigue syndrome (CFS) was the name coined by the Centers for Disease Control (CDC) in response to an outbreak of "chronic flu-like illness" at Incline Village.[2]

Outbreak[edit | edit source]

An estimated 160 residents of Incline Village became ill with chronic fatigue syndrome (CFS) the winter of 1985 of which the majority were seen by local doctors, Paul Cheney and Daniel Peterson.[3]

Dr. Anthony Komaroff studied 175 cases around Lake Tahoe and found "quite a number" have been fully or partially disabled while a third said their condition improved.[4]

Truckee, California High School[edit | edit source]

During this same time, about 20 miles away, Truckee, California was involved in a similar outbreak. Nine of 10 teachers using a conference room at the same high school were found to be suffering from Sick building syndrome (SBS) as well as symptoms typical of CFS.[5][6]

Local response[edit | edit source]

Paul Cheney and Dan Peterson[edit | edit source]

Doctors who practiced at Incline Village and experienced the outbreak first hand include Daniel Peterson and Paul Cheney. They have continued to work in the ME/CFS field.

CDC investigation[edit | edit source]

'The CDC showed up eventually, but they refused to examine any of the patients. Stephen Straus called it a disease of “depressed menopausal women.” HHS made this characterization known to the press, which then dubbed the disease “Yuppie Flu.”'[7]

The local doctors seemed to be defending their scorned and disabled patients from the CDC and medical establishment.[8]

In an interview with Hillary Johnson, she spoke about Incline Village and the CDC response. "In 1984-85, a large number of people living in Incline Village, Nevada, were devastated by a mysterious, debilitating disease, now known to be Chronic Fatigue Syndrome. After a cursory investigation of the outbreak, the Centers for Disease Control (CDC) and the National Institutes of Health (NIH) have made little effort to aggressively research the disease. It was not until 1995--ten years later--that scientists at the CDC gave CFS a "Priority 1" listing among their "New and Reemerging Infectious Diseases" category, thus officially recognizing it as a bona fide disease. Despite including CFS in this category, these agencies continue to insist there is no evidence that CFS is infectious."[9]

Although the CDC did not examine patients when they were sent to investigate the mysterious illness they were called in for, they somehow were able to, at a later date, produce a report based on whether or not the patients were experiencing Chronic Epstein-Barr virus. The non-conclusion was: "Currently available data neither prove nor disprove the hypothesis that EBV activity is responsible for chronic illness, but it is clear that the diagnosis of CEBV using current clinical and laboratory criteria in an individual patient is unreliable."[10]

Causes[edit | edit source]

HHV-6[edit | edit source]

Dr. Paul Cheney theorizes that a particularly virulent strain of HHV-6 swept the population.[11] He found that the sufferers were "mass-producing antibodies to Epstein-Barr virus, the herpes virus that causes infectious mononucleosis." Dr. Cheney contacted the CDC to report the outbreak.[12]

Biotoxin exposure[edit | edit source]

Erik Johnson, a patient who pioneered mold avoidance for CFS, theorizes that an outbreak of toxic cyanobacteria (blue green algae) on Lake Tahoe located near Incline village may have been a causative agent.[13]
