Q Fever: A Major Occupational Zoonotic Disease
Understanding Q Fever in Veterinary Practice
Q fever is a serious occupational zoonotic disease that affects veterinarians, farm workers, and those involved in animal husbandry. It is caused by Coxiella burnetii, a highly infectious bacterium that spreads from animals to humans.
According to the Centers for Disease Control and Prevention (CDC), Q fever remains a significant risk for individuals exposed to livestock and animal products.
How Q Fever Spreads
Primary Sources of Infection
Q fever primarily spreads through:
- Inhalation of contaminated aerosols from birth fluids, feces, urine, and milk of infected animals.
- Direct contact with infected animals, especially during veterinary procedures.
- Consumption of unpasteurized dairy products, as Coxiella burnetii can survive in milk.
High-Risk Occupational Groups
- Veterinarians and vet assistants
- Livestock farmers
- Meat processing workers
- Animal researchers

Symptoms and Complications of Q Fever
Acute Q Fever Symptoms
- High fever
- Chills
- Fatigue
- Muscle pain
- Pneumonia (in severe cases)
Chronic Q Fever Risks
- Endocarditis (infection of the heart valves)
- Chronic fatigue syndrome
- Liver complications
For more on symptoms and complications, check the European Centre for Disease Prevention and Control (ECDC) guide on Q fever.
Diagnosis and Treatment
Diagnostic Methods
- Serological tests to detect antibodies
- PCR testing for early detection
- Blood cultures in chronic cases
Treatment Options
- Doxycycline is the most effective antibiotic.
- Chronic cases require long-term antibiotic therapy.
More information is available at the National Institutes of Health (NIH) Q fever research page.
Preventing Q Fever in Veterinary Settings
Hygiene and Sanitation
- Always wear protective gloves and masks when handling animals.
- Properly dispose of birth products, feces, and urine.
- Regularly disinfect work areas.
Vaccination for High-Risk Workers
- The Q-Vax vaccine is recommended in some countries for those at high risk.
- Pre-exposure screening is needed before vaccination.
Reducing Airborne Transmission
- Use ventilation systems in animal enclosures.
- Wet down contaminated areas before cleaning to reduce dust.
More prevention tips are available from the Food and Agriculture Organization (FAO) Q fever prevention guide.
Q Fever and Veterinary Regulations
Legal Responsibilities of Veterinary Professionals
- Reporting cases to public health authorities.
- Following biosafety protocols in clinics and farms.
- Educating clients about the risks of zoonotic diseases.
Global Guidelines on Q Fever Control
For veterinary professionals, the World Organisation for Animal Health (WOAH) provides detailed guidelines.
Conclusion
Q fever poses a serious health risk to veterinary professionals and livestock handlers. Understanding its transmission, symptoms, and preventive measures is crucial for maintaining safety. For further guidance, refer to the Centers for Disease Control and Prevention (CDC) official Q fever page.
