Wildlife disease surveillance is important for understanding wildlife health and can also provide insight into human and domestic animal health. Monitoring wildlife for diseases can be used to initiate preventative measures or management efforts against outbreaks in other wildlife, domestic animals, and humans. Passive surveillance involves investigation of mortality events to determine the cause(s) of disease. Results of passive surveillance give researchers insight into what is currently causing or has previously caused morbidity and mortality. Active surveillance consists of targeted investigations of pathogens, toxicants, and diseases through systematic collections of animals or their samples. Through various surveillance frameworks, researchers can assess current and future risk to outbreaks and diseases.
