What is Q fever?

Q fever is a bacterial zoonotic disease caused by *Coxiella burnetii*, a small, Gram-negative, obligate intracellular bacterium. The disease was first described in Queensland, Australia, in 1935, and has since been reported in many countries around the world.

Q fever is typically transmitted to humans through contact with infected animals or their products, such as raw milk, placentas, or amniotic fluid. The bacteria can also be spread through inhalation of aerosolized particles from infected animals or contaminated environments.

The incubation period for Q fever is typically 2-3 weeks, but can range from 1 to 6 weeks. The symptoms of Q fever can vary from mild to severe and may include:

* Fever

* Headache

* Muscle pain

* Fatigue

* Chills

* Cough

* Shortness of breath

* Nausea

* Vomiting

* Diarrhea

In some cases, Q fever can lead to more serious complications, such as pneumonia, hepatitis, encephalitis, or endocarditis.

Q fever is typically diagnosed based on the patient's symptoms and a blood test that detects antibodies to *Coxiella burnetii*. Treatment for Q fever usually involves antibiotics, such as doxycycline or ciprofloxacin.

Prevention of Q fever involves avoiding contact with infected animals or their products, and taking precautions to avoid inhaling aerosolized particles from contaminated environments.
