Q Fever Transmission: Routes of Infection

Q fever (Coxiella burnetii) transmission routes:

  • Inhalation (most common): Airborne dust/aerosols from infected animal birth products/feces (goats, sheep, cattle)
  • Animal contact: Direct contact during birthing, slaughtering, handling products
  • Ingestion: Raw/unpasteurized dairy (especially milk) from infected animals
  • Less common: Contaminated soil/water

Occupational exposure (farmers, veterinarians, abattoir workers) carries highest risk.
