Fever of Unknown Origin  

Fever of Unknown Origin is a zoonotic disease caused by the bacterium Coxiella burnetii, which is highly resistant to environmental conditions such as dryness and sunlight. Fever of Unknown Origin is typically not transmitted from person to person; instead, infection occurs through contact with infected animals. Sheep, goats, camels, and cattle are considered the main sources of human infection, primarily through inhalation of dust contaminated with the feces or abortions fluids of infected animals, or through contact with their contaminated wool or skin.  

Groups Most Susceptible to Infection:  

Animal breeders  

Slaughterhouse workers  

Veterinarians and veterinary assistants
