Q fever is an infectious disease caused by a species of bacteria usually found in sheep, goats and cattle. Humans working in livestock occupations may be at risk. Q fever usually spreads to people through the inhalation of contaminated barnyard dust.

Q fever can occur either in an acute or a chronic form. The acute form is milder and characterized by flu-like symptoms. The chronic form lasts longer and has more serious effects on your body.

The name Q fever emerged after the disease was called Query fever following an outbreak in the 1930s in Queensland, Australia. The illness is uncommon, but experts believe it is underreported and often goes unrecognized. It occurs around the world.

With acute Q fever, you'll likely recover fully within a few months with little or no treatment or much sooner after antibiotic treatment. Chronic Q fever requires lengthier treatment.
