Context: <\/strong>Climate change has emerged as one of the greatest health threats of the 21st century. Rising temperatures and extreme weather events are causing heat-related deaths, malnutrition, disease outbreaks and disruptions in healthcare services. Considering this, it is argued that the World Health Organization (WHO) should declare climate change a Public Health Emergency of International Concern (PHEIC) to mobilise international cooperation and protect vulnerable populations.<\/p>\n

Major health impacts of climate change<\/strong><\/h2>\n
    \n
  1. Heat-related mortality: <\/strong>Rising temperatures and prolonged heatwaves are increasing heat-related deaths, particularly among the elderly, pregnant women, children and people with chronic illnesses.<\/li>\n
  2. Maternal and child health: <\/strong>Extreme heat can adversely affect maternal health, pregnancy outcomes and the long-term health of unborn children.<\/li>\n
  3. Malnutrition and food insecurity: <\/strong>Climate-induced crop failures reduce food availability and worsen malnutrition, particularly among children in vulnerable communities.<\/li>\n
  4. Spread of infectious diseases:<\/strong> Changing climatic conditions can intensify disease risks, including malaria, threatening the lives of vulnerable populations.<\/li>\n
  5. Disruption of healthcare services: <\/strong>Floods, cyclones and other extreme weather events can damage healthcare infrastructure, isolate communities from clinics and interrupt access to essential medicines.<\/li>\n
  6. Displacement and livelihood loss: <\/strong>Climate-related disasters force communities to leave their homes, destroy livelihoods and increase their exposure to health risks.<\/li>\n
  7. Impact on healthcare workers: <\/strong>Climate change also affects healthcare workers, reducing their ability to provide essential services to communities in need.<\/li>\n<\/ol>\n

    About Public Health Emergency of International Concern (PHEIC)<\/strong><\/h2>\n
      \n
    1. A PHEIC is defined in the IHR (2005) as, \u201can extraordinary event which is determined to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response\u201d.<\/li>\n
    2. This definition implies a situation that is:\n
        \n
      1. serious, sudden, unusual or unexpected;<\/strong><\/li>\n
      2. carries implications for public health beyond the affected State\u2019s national border; and<\/strong><\/li>\n
      3. may require immediate international action.<\/strong><\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

        Reasons why should WHO declare climate change a PHEIC<\/strong><\/h2>\n
          \n
        1. To recognise the urgency of the crisis: <\/strong>A formal declaration would acknowledge that climate change is an immediate public health threat rather than a distant environmental risk.<\/li>\n
        2. To mobilise international financing: <\/strong>The declaration could help catalyse financial resources for prevention, preparedness and healthcare interventions.<\/li>\n
        3. To strengthen international cooperation: <\/strong>It would facilitate coordinated action among countries and international institutions to address the cross-border consequences of climate change.<\/li>\n
        4. To provide evidence-based recommendations: <\/strong>WHO could support countries with scientific guidance and public health strategies to reduce climate-related health risks.<\/li>\n
        5. To protect vulnerable populations: <\/strong>It would promote an equitable response prioritising those most affected, especially people in developing countries who have limited resources to adapt.<\/li>\n
        6. To improve surveillance and prevention: <\/strong>Greater coordination could strengthen monitoring of climate-related health impacts and enable early identification of emerging risks.<\/li>\n
        7. To overcome slow global action:<\/strong> Despite successive international commitments, progress on climate change has been inadequate, while efforts under the consensus-based UN climate framework have faced delays and setbacks.<\/li>\n<\/ol>\n

          Need of the immediate action <\/strong><\/h2>\n
            \n
          1. Intensifying extreme weather: <\/strong>Heatwaves, floods, wildfires and droughts are affecting communities across the world, causing displacement and loss of life.<\/li>\n
          2. The El Ni\u00f1o factor:<\/strong> It is highlighted the risks associated with an intensifying El Ni\u00f1o, which can aggravate heat and extreme weather conditions.<\/li>\n
          3. Growing evidence of health impacts: <\/strong>Scientific research increasingly demonstrates the contribution of climate change to adverse health outcomes, strengthening the case for urgent public health action.<\/li>\n
          4. Unequal burden of climate change: <\/strong>Countries in the Global South often face greater climate-related risks despite having contributed relatively little to the problem.<\/li>\n
          5. Limited adaptive capacity:<\/strong> Many affected communities understand the risks but lack adequate financial resources and infrastructure to protect themselves.<\/li>\n<\/ol>\n

            How can a PHEIC declaration help<\/strong><\/h2>\n
              \n
            1. Application of International Health Regulations:<\/strong> The WHO can initiate the prescribed assessment process under the International Health Regulations (IHR) to examine whether the situation warrants a PHEIC declaration.<\/li>\n
            2. Expert assessment of risks: <\/strong>An expert committee can evaluate the seriousness and unusual nature of the threat, its potential international spread and the risks of international travel or trade restrictions.<\/li>\n
            3. Coordinated global response: <\/strong>A declaration could strengthen international coordination, public health preparedness and the sharing of scientific knowledge.<\/li>\n
            4. Equitable and preventive action:<\/strong> Countries could prioritise healthcare for affected populations, large-scale prevention and systematic surveillance of climate-related health impacts.<\/li>\n<\/ol>\n

              Conclusion: <\/strong>Climate change is an immediate and unequal public health threat that demands a coordinated international response. The WHO should assess the crisis through the International Health Regulations framework and consider a PHEIC declaration to strengthen financing, prevention, surveillance and international cooperation. Timely action is essential to protect vulnerable populations and prevent avoidable loss of life.<\/p>\n

              Question: <\/strong>Climate change is no longer merely an environmental concern but an escalating public health emergency. Discuss the need for the World Health Organization (WHO) to declare climate change a Public Health Emergency of International Concern (PHEIC).<\/p>\n
