Q fever: a rare but potentially life-threatening zoonotic disease

Q fever can present as a fever of unknown aetiology and can be challenging to diagnose because of the rare incidence. It can present as an acute illness with manifestations, including influenza-like symptoms, hepatitis, pneumonia or chronic disease involving the cardiovascular system. We present a case of a 39-year-old woman in the USA, who developed acute Q fever with associated sepsis and severe hepatitis. She received treatment with recovery from acute infection but currently has symptoms of post Q fever syndrome.
