Overview
Q fever is an infectious disease that is spread by domestic and wild animals and ticks.
What are the symptoms of Q fever?
Common symptoms include:
- Dry cough (nonproductive)
- Fever
- Headache
- Joint pain (arthralgia)
- Muscle pains
Other symptoms that may develop include:
What causes Q fever?
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. You can get Q fever by drinking raw (unpasteurized) milk, or after inhaling dust or droplets in the air that 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. Most 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. Men are infected more often than women, and most people who get Q fever are between 30 and 70 years old. This disease is occasionally seen in children, especially those who live on a farm. In infected children younger than 3 years old, Q fever is usually discovered during a search for the cause of pneumonia.
Who is at highest risk?
You can get Q fever by drinking raw (unpasteurized) milk, or after inhaling dust or droplets in the air that are contaminated with animal feces, blood, or birth products.
When to seek urgent medical care?
In case you feel you are developing symptoms as above and has risk factors, contact your health professional.
Diagnosis
A physical examination may reveal crackles in the lungs or an enlarged liver and spleen. In the late stages of the disease, a heart murmur may be heard. Tests that may be done include:
- A chest x-ray to detect pneumonia or other changes
- Blood tests to check for antibodies to Coxiella burnetti
- Liver function test
- Complete blood count (CBC)
- Tissue staining on infected tissues to identify the bacteria
- Electrocardiogram or echocardiogram to look at the heart
Treatment options
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 pregnant women or children who still have any baby teeth because it can permanently discolor growing teeth.
Where to find medical care for Q fever?
Directions to Hospitals Treating Q fever
What to expect (Outlook/Prognosis)?
Most people get better with 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
Possible complications
Rarely, a heart infection results that can lead to severe symptoms or even death if untreated. Other complications can include:
- Bone infection (osteomyelitis)
- Brain infection (encephalitis)
- Liver infection (chronic hepatitis)
- Lung infection (pneumonia)
