Q fever
ICD-10 A77.3 is a billable code used to indicate a diagnosis of q fever.
Q fever is an infectious disease caused by the bacterium Coxiella burnetii, primarily transmitted to humans from animals, particularly livestock such as cattle, sheep, and goats. The disease is characterized by a wide range of symptoms, including high fever, chills, fatigue, and muscle aches, which can develop into more severe complications such as pneumonia or hepatitis. The incubation period for Q fever typically ranges from 2 to 3 weeks following exposure. Diagnosis is often made through serological testing, which detects antibodies against C. burnetii. The disease is notable for its potential to become chronic, leading to conditions such as endocarditis in susceptible individuals. Q fever is considered a zoonotic disease, meaning it can be transmitted from animals to humans, often through inhalation of contaminated aerosols or dust from infected animal products. Travel-related infections may occur in individuals visiting areas with known outbreaks or high-risk animal populations. Effective prevention strategies include vaccination for at-risk populations and proper handling of animal products.
Detailed patient history, including exposure to livestock and travel history.
Patients presenting with fever and respiratory symptoms after exposure to animals.
Ensure that serological tests are documented and interpreted correctly.
Comprehensive review of symptoms and potential exposure sources.
Patients with flu-like symptoms returning from rural or agricultural areas.
Consider differential diagnoses and document any travel history.
Used when Q fever is suspected based on clinical presentation.
Document the reason for testing and any relevant exposure history.
Infectious disease specialists should ensure comprehensive documentation of test results.
Common symptoms include high fever, chills, fatigue, muscle aches, and in some cases, pneumonia or hepatitis.
Q fever is primarily transmitted through inhalation of contaminated aerosols from infected animals, particularly livestock.
The first-line treatment for Q fever is doxycycline, especially in acute cases.
