Summary of analyzed geographical areas, vectors, environmental factors and main findings of studies dealing with dengue.

	Geographical area	Vector	Analyzed environmental factors	Affected by climate change	Changes in prevalence or incidence due to climate change	Expansion due to climate change	First author [year of publication]
	Main findings
	Worldwidea	Aedes aegypti	Net effect of climate change	No	Decreases	No	29,
	In 2030 Democratic Republic of the Congo, Congo, Gabon, the southern coast of Benin, Nigeria, Togo, Ghana and Ivory Coast will be climatically suitable. Marginal zones include the Western coast of Mauritania and Morocco. In 2070, expansion especially into Lybia and Egypt
	Worldwidea	Aedes aegypti	Average temperature increase, variations in diurnal temperature	Yes	Increases	Yes	30,
	Dengue epidemic potential decreases at more than 29ºC. Increased risk in the Northern hemisphere and parts of Southern Africa
	Worldwidea	Aedes aegypti, Aedes albopictus	Net effect of climate change	Yes	Increases	Yes	46,
	Changes in dengue distribution in 2080. Limiting factor is the absence of Aedes aegypti.
	South and center	Aedes aegypti, Aedes albopictus	Net effect of climate change	Yes	Increases	Yes	25,
	Potential expansion of Aedes aegypti into Southern Africa, occurrence extended into Central Africa. Increased expansive potential than Aedes albopictus, which may also raise
