For a long time, dengue fever is often diagnosed among populations living in tropical and subtropical climates because that is the environment where the Aedes mosquitoes - the vector of the virus - thrives in. But as climate change causes temperatures the rise, the mosquitoes are now able to live and thrive in more temperate countries, exposing more people to the virus. Will this be the wake-up call that the world needs to better address dengue fever - which has yet to have an effective treatment? Joining me to share her insights and what it would mean for dengue to be seen as a global health threat, is Dr Dinu Guruge, an epidemiologist and consultant for the Global Dengue Program under the Drugs for Neglected Diseases Initiative.
