13 September is World Sepsis Day (WSD), a global movement uniting individuals, healthcare professionals, and organisations to confront one of the world’s deadliest yet most preventable conditions.
Since 2012, more than 54,000 stakeholders from 170 countries have joined together each year on 13 September to mark WSD. Participants include policymakers, national health authorities, healthcare providers, researchers, innovators, advocates, survivors, families affected by sepsis, and medical students.
World Sepsis Day was launched by the Global Sepsis Alliance (GSA), the largest international professional and advocacy network dedicated to fighting sepsis. Across Africa, Asia-Pacific, Europe, the Eastern Mediterranean, Latin America and the Caribbean, and North America, GSA members and partners organise a wide range of campaign events, from scientific conferences and training sessions to media outreach and the launch of national, regional, or global initiatives to strengthen sepsis literacy and advocacy.
In 2025, World Sepsis Day marks a new chapter in the global response, placing stronger emphasis on media engagement and public awareness to shed light on this often-invisible threat responsible for one in every five deaths worldwide.
Sepsis is a medical emergency. Forty-nine million cases occur annually. Children under five account for 40% of cases, with the heaviest burden in low- and middle-income countries. Survivors often face long-term physical and cognitive impairments, affecting not only patients and families but also broader economic growth and development.
Yet, most sepsis-related deaths are preventable with timely intervention and existing medical strategies. This year, the GSA spotlights its theme, “5 Facts x 5 Actions,” underscoring essential truths about the burden of sepsis and urgent steps that must be taken to save lives.
Action 1: Make Sepsis a National Health Priority: Health ministries and parliamentary committees must develop and finance national sepsis policies and action plans. These plans should be integrated into broader health reforms and Universal Health Coverage initiatives, including maternal, neonatal, child health, and immunisation programmes. Governments should seek support from bilateral and multilateral donors, the World Bank, development banks, Gavi, and the Global Fund.
Action 2: Develop Protocols and Train Healthcare Providers: National health authorities and professional associations should establish evidence-based clinical guidelines for sepsis care. Protocols must include community and clinical pathways as well as first-hour sepsis bundles for both children and adults. Healthcare workers across all levels, from primary care to emergency teams and ICUs, should receive regular training. Sepsis prevention and management must be embedded in medical and nursing curricula.
Action 3: Mobilise Global Investment in Sepsis Response: Sepsis represents one of the strongest investment cases in global health. The United Nations should call for global investment in sepsis science and capacity-building. Financial institutions (World Bank, IMF), global partnerships (Gavi, Global Fund, UNITAID), philanthropic foundations, and research initiatives (e.g., EU Horizon) should prioritise sepsis research and response. Investment is urgently needed in new vaccines, diagnostics, AI tools, antibiotics, and precision medicine to save millions of lives.
Action 4: Harness the Power of Media: Sepsis kills more people than heart attacks or strokes, yet awareness remains dangerously low. Media can be a game changer by making sepsis a household term and stressing its status as a time-critical medical emergency. Journalists, influencers, and communicators play a key role in holding governments accountable. All media, TV, radio, press, and digital, should report regularly on sepsis and advocate for urgent action.
Action 5: Embed Sepsis in Pandemic and Emergency Preparedness: Every future pandemic will increase sepsis risks; preparedness plans must account for this. Armed conflicts, disasters, and humanitarian crises also increase vulnerability. Governments should ensure sepsis prevention, surveillance, and clinical care are included in emergency response plans.
World Sepsis Day is more than a date. It is a call to action. Every ICU professional, policymaker, survivor, or advocate has a vital role to play. By raising awareness, promoting early detection, and improving access to care, the trajectory of sepsis can be changed, and millions of lives worldwide can be protected.
