Dengue Surge Linked to Climate Change

 

Dengue Surge Linked to Climate Change



    Dengue fever cases are at record levels worldwide, with studies linking 19% of the rise to climate change, which is expected to worsen by 2050. Predictions indicate a potential 40-60% rise in cases, with some areas facing increases of 150-200%.

Current Global Context

    Recently, nearly 12 million dengue cases were reported in the Americas. This marks an important rise from 4.6 million in 2023. Locally acquired infections have emerged in California and Florida. India is also experiencing a surge in cases.

Research Findings

    Researchers from Stanford and Harvard conducted a study on dengue incidence. They analyzed data from 21 countries in Asia and the Americas. The results show a direct correlation between rising temperatures and increasing dengue infections.

    Dengue can cause mild to severe symptoms. Severe cases may lead to bleeding and shock. There are no specific treatments for dengue. Two vaccines exist but face challenges in widespread use.

Impact of Climate Change

    The study marks climate change as an important health threat. Reducing global warming could lessen dengue’s impact. Sharp cuts in emissions could reduce the expected 60% rise in infections to about 40%.

Future Predictions

    Despite potential emission reductions, some countries will still see increases. Of the 21 countries studied, 17 are predicted to experience climate-driven dengue rises. Areas entering the optimal temperature range for virus transmission face the highest risks.

    Mitigating climate change is crucial for controlling dengue. Effective emission cuts can help manage the future burden of this disease.

  Clean Ganga Mission to Start Dolphin Ambulance      The National Mission for Clean Ganga (NMCG) is actively promoting conservation efforts and targeting the Ganga River’s biodiversity. They focus particularly on endangered species like the Ganga Dolphin . Recent developments include the introduction of a Dolphin Ambulance. This vehicle will aid in rescuing injured dolphins, which are crucial to the river’s ecosystem. Dolphin Ambulance Initiative      The Dolphin Ambulance project is titled Advancing Rescue System for the Protection of Stranded Ganges River Dolphins, which has a budget of Rs 1 crore. The ambulance will provide immediate care to injured dolphins. The initiative aims to enhance public awareness about dolphin conservation. Training will be provided to local communities. This training focuses on the effective management of dolphin-related issues. Additional Conservation Projects      NMCG has approved several other proje...
