Psittacosis is caused by a type of bacteria. The bacteria is usually passed to people from a sick bird. It may be inhaled through the dust of dried bird droppings from the sick bird. It can also pass when a person touches his or her mouth to the beak of an infected bird.
The bacteria can pass from one person to another. This is rare.
Contact with a pet bird increases the risk of psittacosis.
Other things that raise the risk are:
- Certain types of work, such as:
- Bird breeder
- Pet shop employee
- Lab worker
- Poultry worker and poultry plant worker
- Zoo or wildlife worker
- Contact with certain birds, such as:
- Parrots, and macaws
- Parakeets and cockatiels
- Turkeys and other poultry
Psittacosis may cause:
- Fever and chills
- Problems breathing
- Sore throat
- Muscle aches
- Chest pain
The doctor will ask about your symptoms and health history. A physical exam will be done.
A blood test can confirm the diagnosis. Other body fluids, such as sputum, may be tested. A chest x-ray may be done to check the lungs.
The goal of treatment is to clear the infection. Psittacosis is treated with antibiotics.
Sometimes severe breathing problems may happen. This is rare but may require a stay in the hospital. Oxygen will make breathing easier. IV antibiotics will also be given.
To reduce the risk of psittacosis:
- Wear a mask, gloves, eyewear, and protective clothing when caring for a sick bird.
- Avoid mouth-to-beak contact with birds.
- Learn about proper bird care and keeping them healthy.
- Take sick birds to the vet right away.
