Q Fever: A Troubling Disease and a Challenging Diagnosis

Abstract

Abstract Q fever is a disease caused by the bacterial pathogen Coxiella burnetii. This hardy organism can easily spread long distances in the wind, and only a few infectious aerosolized particles are necessary to cause serious illness. Presentations of Q fever disease can be wide ranging, allowing it to masquerade as other illnesses, highlighting the importance of laboratory testing for diagnosis and treatment. This review summarizes Q fever s epidemiology and clinical presentations and presents classical laboratory diagnostic assays and novel approaches to detecting this troubling disease.
