Compendium of Measures to Control Chlamydia psittaci Infection Among Humans (Psittacosis) and Pet Birds (Avian Chlamydiosis), 2017.

Psittacosis, also known as parrot fever and ornithosis, is a bacterial infection that can cause severe pneumonia and other serious health problems in humans. It is caused by Chlamydia psittaci. Reclassification of the order Chlamydiales in 1999 into 2 genera (Chlamydia and Chlamydophila) was not wholly accepted or adopted. This resulted in a reversion to the single, original genus Chlamydia, which now encompasses all 9 species including Chlamydia psittaci. During 2003-2014, 112 human cases of psittacosis were reported to the Centers for Disease Control and Prevention through the Nationally Notifiable Diseases Surveillance System. While many types of birds can be infected by C psittaci, in general, the literature suggests that human cases can most often occur after exposure to infected parrot-type birds kept as pets, especially cockatiels, parakeets, and conures. In birds, C psittaci infection is referred to as avian chlamydiosis. Infected birds shed the bacteria through feces and nasal discharges, and humans become infected from exposure to these materials. This compendium provides information about psittacosis and avian chlamydiosis to public health officials, physicians, veterinarians, the pet bird industry, and others concerned with controlling these diseases and protecting public health. The recommendations in this compendium provide standardized procedures to control C psittaci infections. This document will be reviewed and revised as necessary, and the most current version replaces all previous versions. This document was last revised in 2010. Major changes in this version include a recommendation for a shorter treatment time for birds with avian chlamydiosis, additional information about diagnostic testing, including genotyping, clearer language associated with personal protective equipment recommended for those caring for confirmed or exposed birds, and incorporating a grading scale with recommendations generally based on the United States Preventive Services Task Force's methods.

Burden of Bites by Dogs and Other Animals in Los Angeles County, California, 2009-2011.

OBJECTIVES: The objective of this study was to analyze all animal-to-human bite reports during a 3-year period from a regional surveillance database. Results helped to inform local efforts to reduce and prevent animal-to-human bites. METHODS: We reviewed all cases of animal-to-human bites occurring from 2009 through 2011 that were reported to the Los Angeles County Department of Public Health's Animal Bites Database. We collected data on the bite victim's date of birth, age, and address; bite circumstances (ie, date, time, location, how bite occurred); anatomic site and treatment of bite; type of reporting facility; and breed and management of biting animal. RESULTS: From 2009 through 2011, 26   169 animal-to-human bites were reported, of which 23   103 (88%) were dog bites. Most animal-to-human bites (n = 7673, 29%) occurred between 4 pm and 8 pm and peaked during the month of July (n = 2663, 10%). Most animal-to-human bites occurred outdoors (n = 8772, 34%) and while victims engaged in recreational activities (n = 4353, 17%). The hands were the most common injury site (n = 9130, 35%), and only 1% of animal bites (n = 267) resulted in hospitalization. A total of 4115 bite victims (16%) received tetanus vaccinations. Of all animal-to-human bite cases, medical organizations reported 13   451 (51%), and animal control agencies reported 10   682 (41%). CONCLUSIONS: Animal-to-human bites can often lead to medical complications. Surveillance is essential in helping to identify, manage, and reduce these highly preventable injuries and direct public health actions and policies on animal bite risk and prevention.

Border health: who's guarding the gate?

Changes in the global trade market have led to a thriving international pet trade in exotic animals, birds, and puppies. The flood of animals crossing the United States' borders satisfies the public demand for these pets but is not without risk. Imported pets may be infected with diseases that put animals or the public at risk. Numerous agencies work together to reduce the risk of animal disease introduction, but regulations may need to be modified to ensure compliance. With more than 280,000 dogs and 183,000 wildlife shipments being imported into the United States each year, veterinarians must remain vigilant so they can recognize potential threats quickly.
