Increasing global temperatures wrought by greenhouse gas emissions have boosted the number of dengue cases, new research shows.

Linking how global warming affects health — such as driving outbreaks or spreading disease — remains a new field

In India, the number has increased from 2,33,251 with 303 deaths in 2022 to 2,89,235 cases in 2023 with deaths increasing to 485, according to government data

Team then looked at 21 dengue endemic countries, including Brazil, Peru, Mexico, Colombia, Vietnam and Cambodia, which regularly collect data on infection rates.

Climate change is responsible for a 19% increase in dengue cases, highlighting the growing health risks linked to environmental changes.

Climate change has the potential to spark an additional 40-60 per cent spike by 2050 — and by as much as 150-200 per cent in some areas — according to a study

Countries in the Americas have recorded nearly 12 million cases of dengue in 2024, compared to 4.6 million in 2023, and locally acquired infections have been reported in California and Florida, say re

Climate change is responsible for nearly a fifth of the record number of dengue cases worldwide this year, US researchers said on Saturday, seeking to shine a light on how rising temperatures help spread disease.

Amid record year for dengue infections globally, a new study has found that climate change is responsible for 19 per cent of rising dengue burden.

About 19% of current dengue cases can be tied to climate change, which has expanded the area within which mosquitos transmit disease both in the United States and around the world, researchers report.
