Climate change increases dengue risk in Keralam; cases may rise by 20% by 2040, says study
A new study warns that climate change could boost dengue fever incidence in Kerala by about 20% by 2040. Researchers pinpoint increased rainfall, humidity and the El Niño‑Southern Oscillation as primary factors. They also note that shifts in atmospheric pressure, temperature and relative humidity during both active and break monsoon periods can promote mosquito breeding, heightening local transmission risk.
