Climate change and variability may also influence the emergence of vector-, food- and water-borne diseases . Under RCP8.5, the epidemic potential of dengue fever in Southern Europe is projected to increase by 2100 , as well as the risk of infections by West Nile virus in 2050 under A1B . Climate-induced diseases could reduce labour productivity in the region by 2060, particularly in MENA countries . Overall, there is still uncertainty in projections of the future severity and distribution of diseases because of climate change due to the complex interactions between hosts, pathogens and vectors. Reductions in fruit and vegetable consumption as a result of climate change on food availability could lead to more than 20,000 deaths in 2050 under RCP8.5 from diseases caused by malnutrition .
