Q fever: A bacterial infection caused by Coxiella burnetii, often transmitted from animals to humans, which can cause flu-like symptoms and potentially lead to complications affecting various organs or systems.
Q fever is a bacterial infection caused by the organism Coxiella burnetii, often transmitted to humans from animals such as cattle, sheep, and goats. The bacteria can spread through inhalation of contaminated air, direct contact with infected animals, or consumption of unpasteurized dairy products. People infected with Q fever may experience flu-like symptoms such as high fever, severe headache, fatigue, and muscle aches. While many individuals recover without treatment, the infection can lead to more severe complications, including pneumonia, hepatitis, or chronic Q fever, which affects the heart and other organs. Early diagnosis and appropriate antibiotic treatment are crucial in managing the disease effectively.
Symptoms and Diagnosis
Q fever symptoms can range from mild to severe and typically appear 2-3 weeks after exposure. Common symptoms include high fever, chills, night sweats, fatigue, and muscle pain. In some cases, it can progress to pneumonia or hepatitis. Diagnosis often involves blood tests to detect antibodies against Coxiella burnetii.
Treatment Options
Acute Q fever is generally treated with antibiotics such as doxycycline, which is most effective when started early in the infection. Chronic Q fever may require a prolonged course of antibiotics and specialist care to prevent serious complications.
Prevention Tips
- Avoid contact with livestock, especially during birthing periods.
- Ensure proper handling and disposal of animal products and waste.
- Consume only pasteurized milk and dairy products.
- Practice good hygiene and use protective equipment if working in high-risk environments.
