health 🦟 El Niño gives dengue a three-month heads-up in Kerala
A new study found that dengue burden in Kerala is linked to monsoon rainfall, temperature, humidity, and El Niño. The state typically sees about 5,000 cases annually, with spikes reaching 21,993 in 2017 and 20,088 in 2024. Researchers project dengue incidence could rise 16%–20% between 2021 and 2040. El Niño conditions offer a potential three-month predictability window for health planners. This research aims to enhance prevention strategies against rising dengue cases.
