Wildlife health surveillance: Gaps, needs and opportunities

May 31, 2023

Disease emergence represent a global threat for public health, economy, and biological conservation and most of the emerging diseases have zoonotic origin from wildlife. To prevent their spread and to support the implementation of control measures, disease surveillance and reporting systems are needed, and due to globalisation, these activities should be carried at world level. To define the main gaps affecting the performances of wildlife health surveillance and reporting systems at word level, we analysed the Wildlife Disease Surveillance Survey submitted to all Members of World Organisation for Animal Health which inquire on structure and limits of surveillance and reporting systems. The response from 103 Members, covering all world areas, showed that 54.4% of them have a wildlife disease surveillance programme and 66% implemented a strategy to manage their spread. The lack of dedicated budget affected the possibility of outbreak investigations, sampling collection and diagnostic testing. Although most Members maintain records relating to wildlife mortality or morbidity events in centralised databases, data analyses and disease risk assessment are reported as main needs. Our evaluation of surveillance capacity showed an overall low level associated to great variability between Members not restricted to specific geographical area. A better recognition of the value of wildlife disease surveillance resulting in allocation of adequate resources by governments would make wildlife disease surveillance systems more functional. Moreover, the future comprehension of the influence of socio-economic, cultural and biodiversity aspects will be essential to increase better disease surveillance under One Health approach.
