Pinjarra Doctors is registered to provide Q Fever vaccination.

Q Fever was first recognised in Australia during the 1930's when workers at a Brisbane meat processor became ill with a fever as the cause of the illness was unknown, the workers were diagnosed with 'Query' fever. This was eventually abbreviated to Q Fever. with the possible exception of a few European countries and New Zealand, cases of Q Fever have been reported worldwide and from every State and Territory in Australia.

The organism, Coxiella burnetii, that causes Q Fever in humans can exist in a variety of domestic and wild animals without the animal displaying apparent signs of infection. In Australia C. burnetii is maintained in the wild by bush animals such as kangaroos, bandicoots and rodents and their attendant ticks. Mutually coexistent ticks may involve feral and domestic goats, cattle or sheep which in turn infect their attendant ticks.

Infection could occur via skin abrasions and splashes of infected material into the eye. The consumption of unpasteurized milk from infected cows and goats has accounted for small numbers of Q Fever cases yet, in some instances, drinking infected raw milk has had an immunising effect in the absence of a clinical disease. Human to human infection is very uncommon as is infection from tick bites.
