The guidelines herein are based on available evidence and may require updating in the fu- Rather than recommending a rigorous screening protocol to identify animal carriage of specific patho- gens, the guidelines place a major emphasis on all indi- viduals (patients and staff) practicing hand hygiene before and after handling animals, as well as on other infection prevention and control strategies to minimize the spread of pathogens from or to animals. The need for facilities to delegate a single individual—an animal visit liaison—to be aware of all animals entering the premises is also identified. Similarly, a method to facil- itate contact tracing in the event of potentially zoonotic patient infections (or handler/animal contact with con- and supported by limitedclinical or epidemiologic Because animals may interact with various popula- tions that may be at risk of infection or injury, certain re- strictions on animal species, age, origin, behavior, diet, and health status are recommended for animals in for- mal AAI programs, whether these programs are run bythe HCF itself or by an external agency. For visits by pa-tients’ pets, the emphasis is placed on animals meeting Table 2. Level of consensus agreement among members certain basic health and diet requirements, and also on limiting human contact during the visit to the relevant patient only (ie, no other patients or staff). Animal visi-tors falling outside of these 2 categories (eg, those brought in by well-meaning community members with no training in AAI) should be denied entry.
