Dengue fever will become a major threat in the southern United States, southern Europe and new parts of Africa this decade, the WHO's chief scientist said, as warmer temperatures create the conditions for the mosquitoes carrying the infection to spread.
With global temperatures rising and increases in human migration, common diseases only in Africa and equatorial climates (Dengue, Malaria, Cholera, Yellow Fever…etc) are likely to migrate up to the global north as well.
