Psittacosis (ornithosis, parrot fever, chlamydiosis)

What is psittacosis?

Psittacosis is an infectious disease usually transmitted to humans from birds in the parrot family, turkeys and pigeons. Birds in the parrot family, or psittacines, include parrots, macaws, budgerigars (parakeets), and cockatiels. The disease is caused by a bacteria called Chlamydophila psittaci.

Who gets psittacosis?

Because this disease is spread by birds in the parrot family, it is occasionally found in pet store workers and people who have purchased an infected bird. It may also be found in farmers and slaughterhouse workers who process turkeys.

How is psittacosis spread?

Psittacosis is usually spread by inhaling dust from dried droppings from bird cages and by handling infected birds in slaughterhouses. Human-to-human spread has not been reported. Waste material in the bird cage may remain infectious for weeks.

What are the symptoms of psittacosis?

In humans, the symptoms are fever, headache, chills and sometimes pneumonia. Some people may only experience mild flu-like illness, or show no illness at all. In birds, the symptoms include poor appetite, ruffled appearance, eye or nose discharge and diarrhea. Occasionally, birds may die from psittacosis. Some birds may shed the organism while exhibiting no symptoms.

How soon after infection do symptoms appear?

The incubation period typically ranges from five to 14 days, but longer incubations have been reported.
