Ornithosis, also known as psittacosis or avian chlamydiosis, is a bacterial infection that mainly affects birds but can also be spread to humans. It is caused by the bacterium Chlamydia psittaci. In birds, the infection can lead to symptoms such as respiratory problems, nasal discharge, lack of energy, and decreased appetite. Humans can get ornithosis through exposure to infected birds or their droppings, feathers, or respiratory fluids. In humans, symptoms may include fever, headache, muscle aches, cough, and difficulty breathing. Ornithosis can vary in seriousness, with some cases causing mild flu-like symptoms and others leading to more serious respiratory illness or pneumonia. Treatment typically involves antibiotics, and preventive measures include avoiding contact with infected birds and practicing good hygiene when handling birds or cleaning cages.
