Psittacosis is transmitted to humans mainly through inhalation of aerosols containing the organism from infected birds. When birds shed chlamydiae in urine, feces, or respiratory secretions, dust or droplets can form and be inhaled, leading to infection. This airborne route explains why exposure to birds or environments with birds (pet birds, poultry workers) is a risk. Eating undercooked poultry is not a typical route for psittacosis—other pathogens are more common there. Drinking contaminated water or skin contact with soil are also not recognized transmission routes for this disease.
