Chronic fatigue syndrome
Chronic fatigue syndrome (CFS) was a name coined by the Centers for Disease Control (CDC) in response to an outbreak of "chronic flu-like illness" in Incline Village, Lake Tahoe in 1984-1985 and several outbreaks and sporadic cases in the United States during the 1980s.
Prior to Incline Village, chronic fatigue syndrome was known as myalgic encephalomyelitis. The "chronic fatigue syndrome" outbreaks of the 1980s and 1990s were likely ME outbreaks, although they differed in some respects from the 1930s-1960s outbreaks. With the development of the 1991 Oxford criteria and the 1994 Fukuda criteria for CFS, which differed in significant respects from historic descriptions of ME, CFS became a wastebasket diagnosis that included patients with ME along with those suffering from a wide range of undefined or misdiagnosed fatiguing illnesses.
