Q fever
ICD-10 A78 is a billable code used to indicate a diagnosis of q fever.
Q fever is an infectious disease caused by the bacterium Coxiella burnetii, which is primarily transmitted to humans through inhalation of contaminated aerosols from infected animals, particularly livestock such as cattle, sheep, and goats. The disease can manifest in acute and chronic forms, with acute Q fever presenting as a flu-like illness characterized by fever, chills, fatigue, and muscle aches, often accompanied by pneumonia or hepatitis. Chronic Q fever, although less common, can lead to serious complications such as endocarditis. Diagnosis is typically made through serological testing for specific antibodies against C. burnetii. The disease is notable for its potential to be asymptomatic, complicating both diagnosis and reporting. Q fever is classified as a zoonotic disease, emphasizing the importance of understanding its transmission dynamics, particularly in agricultural settings. Travel-related infections may arise in individuals exposed to infected animals or contaminated environments, making awareness of Q fever crucial for travelers visiting endemic areas. Effective public health measures, including vaccination of livestock and proper handling of animal products, are essential for prevention.
Detailed patient history including exposure risks, symptom onset, and serological test results.
Patients presenting with fever, pneumonia, or hepatitis after exposure to livestock.
Ensure clear differentiation between acute and chronic forms of the disease.
Comprehensive patient history and physical examination findings, including travel history.
Patients with flu-like symptoms returning from endemic areas.
Consideration of differential diagnoses and appropriate referrals to specialists.
Used to confirm diagnosis of Q fever in symptomatic patients.
Document the reason for testing and clinical findings.
Infectious disease specialists should ensure comprehensive testing for accurate diagnosis.
Common symptoms include high fever, chills, fatigue, muscle aches, and in some cases, pneumonia or hepatitis.
Diagnosis is typically made through serological testing for antibodies against Coxiella burnetii, along with a thorough patient history.
Preventive measures include vaccination of livestock, proper handling of animal products, and avoiding exposure to contaminated environments.
