Ann. Méd. Vét., 2006, 150 (1), pp 56-63 Influence of global climate changes on arboviruses spreadTOUSSAINT J.-F., KERKHOFS P., DE CLERCQ K.Abstract :
The simultaneous progression of several arboviruses and changes of the world climate suggest that both phenomenons might be linked to each other. The analysis of many observations indeed supports an implication of global warming, rainfall modifications and extreme climatic events on the distribution of arboviruses like bluetongue, African horse sickness, dengue, Rift valley fever and West Nile fever. Climate changes might however not fully explain such a fast spread of
arboviruses. The recent evolution of anthropic activities like travel, transport of goods and animals, urbanization and land use also have a considerable incidence on arboviruses progression.
Although the arboviral cycles are often complex and the forcasts about future climate changes remain associated with high uncertainties, the arguments that are described further support a future modification of arboviruses distribution due to climate changes.
