Surveillance for Emerging Biodiversity Diseases of Wildlife

Abstract

[Extract] Effective surveillance is crucial for early detection and successful mitigation of emerging diseases [1]. The current global approach to surveillance for wildlife diseases affecting biodiversity ("biodiversity diseases") is still inadequate as demonstrated by the slow characterization and response to the two recent devastating epidemics, chytridiomycosis and white-nose syndrome [2]–[5]. Current surveillance for wildlife disease usually targets diseases that affect humans or livestock, not those impacting wildlife populations. Barriers to effective surveillance for biodiversity diseases include a relative lack of social and political will and the inherent complexity and cost of implementing surveillance for multiple and diverse free-ranging populations. Here we evaluate these challenges and the inadequacies of current surveillance techniques, and we suggest an integrated approach for effective surveillance.
