(Parrot Fever, Ornithosis)
Psittacosis is caused by the bacteria Chlamydophila psittaci. It is also known as parrot fever or ornithosis. It is transmitted to humans from infected birds. Birds from the parrot family are the most common carriers; less common carriers are poultry, pigeons and sea birds. Though rare, people who own pet birds or work with birds (e.g., at pet shops, veterinary clinics, farms) are most at risk. Symptoms include fever, headache, rash, muscle pain and respiratory symptoms.
