Case report: Possible psittacosis in a military family member-clinical and public health management issues in military settings.

ABSTRACT

Chlamydia psittaci infection among humans (psittacosis) and pet birds (avian chlamydiosis), also known as parrot disease, parrot fever, and ornithosis, is a zoonotic bacterial disease. Humans most often become infected by inhaling the organism when urine, respiratory secretions, or dried feces of infected birds are dispersed in the air as very fine droplets or dust particles. C. psittaci infection of humans can cause influenza-like symptoms, such as fever of abrupt onset, pronounced headache, and dry cough, and can lead to severe pneumonia and non-respiratory health problems. Infection can also be asymptomatic. There is no vaccine for this infection. The disease is treatable with a tetracycline antibiotic, usually doxycycline, or a second-line therapy such as erythromycin or azithromycin. With appropriate treatment, the infection is rarely fatal. This report describes a case of severe, community-acquired pneumonia possibly due to C. psittaci in a resident of Colorado and examines significant clinical and epidemiological characteristics of psittacosis that affect confirming the diagnosis and managing the risks of exposure to psittacine (parrot-type) birds.
