Chlamydia psittaci is a type of bacteria that often infects birds. Less commonly, these bacteria can infect people and cause a disease called psittacosis. Psittacosis causes a wide range of symptoms, including fever, headache, and a dry cough. This illness can also cause pneumonia (a lung infection) that may require treatment or care in a hospital. Rarely, psittacosis can be deadly.
