What’s really to blame for the rise in dengue? | Wellcome
Dengue is a viral infection that spreads from mosquitoes to people. It’s usually found in warm climates and isn’t as deadly as other mosquito-borne diseases like malaria. But half of the world is now at risk. In this explainer video featuring Dr Felipe Colón-González and Dr Sophie Yacoub, we discuss how we can protect more people from dengue — as well as the big reasons behind the recent surge in cases.
