Local thermal anomalies and the altitudinal rise of dengue hospitalisation rates in Ecuador, 2011–2024: a national ecological study
Introduction Dengue is expanding beyond its traditional lowland range as rising temperatures may enable Aedes aegypti establishment at progressively higher altitudes. Ecuador, spanning sea level to above 4500 m, offers a natural altitudinal experiment, yet hospital-based evidence on the thermal drivers of Andean dengue...
