Slide 1 : Q fever - early
Slide 2 : Overview Q fever is an infectious disease that is spread by domestic and wild animals and ticks.
Slide 3 : Symptoms *Dry cough (non-productive) *Fever & Headache *Joint pain (arthralgia) & Muscle pains *Abdominal pain *Chest pain & Jaundice & Rash
Slide 4 : Treatment Treatment with antibiotics can shorten the length of the illness. Antibiotics that are commonly used include tetracycline and doxycycline. Tetracycline given by mouth should not be used by children who still have any baby teeth, because it can permanently discolor growing teeth.
Slide 5 : Causes Q fever is caused by the bacteria Coxiella burnetii, which lives in domestic animals such as cattle, sheep, goats, birds, and cats. Some wild animals and ticks also carry the bacteria. People get Q fever after exposure to raw (unpasteurized) milk, or after inhaling dust or droplets in the air which are contaminated with animal feces, blood, or birth products. Symptoms usually develop 2 to 3 weeks after coming in contact with the bacteria. This is called the incubation period. Some people may have no symptoms; others may have moderately severe symptoms similar to the flu. If symptoms occur, they may last for several weeks. People at risk for infection include slaughterhouse workers, veterinarians, researchers, food processors, and sheep and cattle workers.
Slide 6 : Tests & diagnosis *A chest x-ray often shows pneumonia or other changes *Antibodies for Coxiella are sometimes found in the blood *Liver function test results may be higher than normal *Low blood counts can develop *Special stains may be done on infected tissues to identify the bacteria *Tests may be performed to determine if the disease has affected the heart A physical examination may reveal crackles in the lungs and an enlarged liver and spleen. In addition:
Slide 7 : Prognosis You will get better even without treatment. However, complications can be very serious and sometimes even life-threatening. Q fever should always be treated if it is recognized as the cause of symptoms.
Slide 8 : Prevention Pasteurization of milk destroys the bacteria that cause early Q fever. Domestic animals should be inspected for signs of Q fever if people exposed to them have developed symptoms of the disease.
Slide 9 : Complications *Bone infection (osteomyelitis ) *Brain infection (encephalitis) *Heart valve infection (endocarditis ) *Infection returns *Liver infection (chronic hepatitis) *Lung infection (pneumonia )
Slide 10 : When to contact a doctor Call your health care provider if you develop symptoms of Q fever. Also call if you have been treated for Q fever and symptoms return or new symptoms develop.
