Abstract

Global change is associated with an emerging or re-emerging risk of zoonotic and vector-borne infectious diseases. Changes in bio-climatic parameters can modify the distribution range of vectors or increase the infectious risk in endemic areas in a multimodal way. Other factors with a potential link to climatic conditions are involved, such as changing landscapes, increased international trade, changes in animal or plant biodiversity, etc., and should not be underestimated in risk assessment. This review describes a non-exhaustive list of vector-borne or zoonotic infectious diseases whose emerging risk depends on global change (dengue, chikungunya, Zika, West-Nile, Usutu, lesihmaniasis, tick-borne encephalitis, Crimean-Congo haemorrhagic fever and hantaviruses). Given the complexity of transmission cycles, emerging risk surveillance and prevention must be multidisciplinary, based on the One Health model.
