As temperatures rise and rainfall patterns shift, vector‑borne diseases like dengue, malaria, and chikungunya are spreading to new places and lasting longer each year. Climate change is altering where and how mosquitoes thrive—turning environmental change into a growing health threat. This World Environment Day, MSF highlights how protecting the environment is essential to protecting health. Stronger prevention, early detection, and access to care are critical to stop vector‑borne diseases from putting more lives at risk.
