Clinical manifestations of Q fever in adults and children.
Q fever is a common zoonosis with almost a worldwide distribution caused by Coxiella burnetii. Farm animals and pets are the main reservoirs of infection and transmission to humans is usually via inhalation of contaminated aerosols, which may be carried by the wind far from the original source of infection. Occupational groups with close association with farm or wild animals are most at risk, however travellers occasionally become infected. The disease is associated with a wide spectrum of clinical manifestations and symptoms, ranging from asymptomatic infection to fatal disease. Awareness of the disease and newer diagnostic methods led to increase of recognition and detection in cases with various or multiple symptoms in adults and children. However, children seem to be less frequently symptomatic and may have milder disease. This review of Q fever cases examines clinical manifestations and symptoms of Q fever in both adults and children and shows that certain symptoms and their severity have altered presentation in children with acute and chronic Q fever when compared to adults.
