ECDC assessment: Chikungunya virus disease and dengue are endemic in large regions of the intertropical convergence zone. Environmental conditions for the growth of mosquito populations are currently improving in Europe, but they are still unfavourable for the virus multiplication in the vector. The likelihood of sustained autochthonous dengue virus transmission in continental Europe associated with introduction by a returning traveller therefore remains low.
