Q fever is caused by a rickettsial organism - Coxiella burnetii and causes a feverish flu-like disease in people. Signs may persist for weeks to months. It rarely causes death. It can also cause a more chronic disease and affect the liver or heart, especially in those with compromised immune systems. The organism is shed in large amounts in the placenta of sheep (also cats). The organism can be air borne so transmission can occur through inhalation of the organism. It can also be spread through contact with materials that have been contaminated with placental fluids.

Prevention

• Take extra precautions around pregnant sheep, especially at lambing. Work in well ventilated areas when possible. Surgical masks are not protective, so those at higher risk should consider the use of a respirator.
• Treat all waste as infectious and disinfect areas well. Use gloves and/or good handwashing techniques when working with sheep.
