and mosquitoes. Environmental factors also contribute substantially to disease, including housing density, ease of cleaning/disinfection, extremes or fluctuations of temperature, and air quality, among others. Environmental stressors such as loud or unfamiliar noises, unfamiliar stimuli, and unpredictable events are additional contributors. Thus, no single factor results in disease; rather, disease results from a combination of factors.

      The importance of adhering to traditional general principles of infectious disease control must never be overlooked in an animal shelter. These include:

      1 Vigilant surveillance and early recognition of disease.

      2 Removal of infected animals (through isolation, transfer to foster care or other veterinary or rescue partners with adequate facilities, or euthanasia).

      3 Mass vaccination and/or mass treatment.

      4 Good husbandry and wellness practices (animals and environment).

      5 Continual education and training of personnel.

      Ultimately, disease control is best addressed proactively by establishing and implementing wellness protocols. Please see the Introduction in Chapter 1 for more information on the principles of infectious disease control in a shelter.

      2.2.4.1 Population Management and Capacity for Care

      In the field of shelter medicine, the term population management is used to refer to an active daily process of planning involving ongoing evaluation and efficient response as an organization cares for multiple animals (Newbury and Hurley 2013). Providing efficient evaluation and care of animals is the key to minimizing each animal's length of stay (LOS) in the shelter, and therefore reducing their risk for the development of disease and problem behaviors. When populations are efficiently managed, wellness care is effectively delivered to support the physical and behavioral health of animals and their environment, increasing the animals' resistance to disease as well as their emotional resilience. In order to be effective, population management must take into consideration an organization's ability and resources to provide care.

      The maximum daily population in an animal shelter that allows for maintenance of recommended standards of care has been defined by the Association of Shelter Veterinarians' Guidelines for Standards of Care in Animal Shelters (2010) as “capacity for care.” Many factors impact a shelter's capacity for care including the availability of housing, staffing, and all other resources necessary to provide humane care. When sheltering organizations operate without sufficient resources to provide proper animal care, animal health and welfare are compromised. Increases in the prevalence of infectious diseases are common, and likewise, increases in displays of fear, anxiety, stress and frustration‐related behaviors by resident animals can be expected. The delivery of effective population management and operating within an organization's capacity for care are both key requirements for the successful implementation of a shelter wellness program. Please see the Introduction in Chapter 1 for more information about population management.

      In animal shelters, it is important to have efficient systems that allow for the assessment of individual animals while affording consideration to the population itself. Indeed, shelter medicine represents a unique blend of both individual patient and population medicine. A useful system for patient evaluation is known as the “problem‐oriented approach,” which is widely accepted as the gold standard for small animal patient care and assessment.

      The problem‐oriented approach is used to systematically identify and address an animal's problems. With this approach, the clinical reasoning process is based on four steps: (i) database collection, (ii) problem identification, (iii) plan formulation, and (iv) assessment and follow‐up. This approach enables the clinician to logically approach each patient to ensure thorough and accurate assessment so that appropriate and timely actions can be taken. A thorough, written or computerized medical record that includes all elements of the animal's assessment and care must be maintained for each patient. See the section later in this chapter on medical record keeping and data collection for more information.
