A billion people will be newly exposed to diseases like dengue fever as world temperatures rise

Science Daily  March 28, 2019
An international team of researchers (USA – University of Florida, South Africa) applied an empirically parameterized model of viral transmission by the vectors Aedes aegypti and Ae. albopictus, as a function of temperature, to predict cumulative monthly global transmission risk in current climates and compare them with projected risk in 2050 and 2080 based on general circulation models. According to the researchers climate-driven risk of transmission from both mosquitoes will increase substantially, even in the short term, for most of Europe. In contrast, significant reductions in climate suitability are expected for Ae. albopictus, most noticeably in southeast Asia and west Africa. Within the next century, nearly a billion people are threatened with new exposure to virus transmission by both Aedes spp. in the worst-case scenario…read more. Open Access TECHNICAL ARTICLE
