Other names for Q fever include Nine Mile fever, Australian Q fever, and Balkan influenza.
Q fever was first discovered in 1935 in workers in slaughterhouses in Australia. Dr. Derrick is credited with discovering the bacterial infection, although the pathogen was still unknown at the time. Because doctors did not know what caused the disease and had ‘queries,’ Q fever was known as query fever.
Around the same time, in Nine Mile, Montana, in the United States, a pathogen was isolated and named the ‘Nine Mile agent.’ Eventually, a person in Nine Mile, Montana, fell ill when handling Q fever samples shipped from Australia, establishing a potential link between Q fever and the Nine Mile fever.
