Climate Change Results in Emerging Diseases

Mosquitoes—and the viruses that they carry—are pushing up the incidence of malaria globally and causing periodic explosive outbreaks of Rift Valley fever, which first brings on flulike symptoms but can turn into a severe hemorrhagic fever akin to Ebola. Bluetongue virus, a ruminant virus spread by midges that was once confined to tropical areas, has reached as far as Norway. Studies have shown shifts in cholera transmission with recent climate variability. As emerging diseases migrate to new areas, they encounter new species, making outbreaks even more difficult to manage.
