Principles of disease prevention, diagnosis, and control

Disease prevention and control involves the three interrelated processes of bioexclusion, surveillance, and biocontainment. Disease prevention, diagnosis, and control strategies have changed to prevent physiological, nutritional, and agent-induced pathologies from affecting performance. Disease control strategies are designed to reduce the consequence of disease challenge by limiting challenge (bioexclusion), enhancing bird resistance (immunization), and preventing spread (quarantine). Control measures are implemented routinely for diseases that are endemic to the epidemiological unit and sporadically when there is an unexpected epidemic disease outbreak. This chapter provides a brief overview of public health issues for several infectious diseases that are common to poultry and humans. It provides a short synopsis of the disease manifestations in humans and may serve as a starting point for further inquiry. Diseases are presented alphabetically within categories defined by the type of infectious agent (i.e., viral, bacterial, fungal, and parasitic).
