The International Day of Epidemic Preparedness, observed annually on December 27, underscores the necessity of global collaboration to address epidemic threats.
Proclaimed by the United Nations (UN) in 2020, this day honors lessons from past crises like COVID-19, emphasizing the importance of readiness in safeguarding lives and economies.
A recent World Health Organization (WHO) report revealed a troubling decline in health spending, threatening epidemic resilience by weakening critical systems for surveillance, prevention and treatment. Simultaneously, the resurgence of mpox in 2024 underscores the risks posed by under-resourced health systems and rising human-to-human transmission. Meanwhile, expanded malaria vaccine access in 17 countries offers hope, poised to save tens of thousands of lives annually.
Dive into this blog to explore how 2024 builds on pivotal lessons from 2023, including innovative vaccines, AI-driven outbreak tracking and global partnerships tackling threats like cholera and malaria to enhance epidemic resilience.
Why Epidemic Preparedness and Collaboration Matter
Epidemics can devastate communities, economies and healthcare systems.
Preparing for these events involves strengthening early detection systems, expanding vaccine distribution networks and addressing critical public health gaps. The WHO’s global strategies, such as the Eliminate Yellow Fever Epidemics (EYE) Strategy and the Ending Cholera: A Global Roadmap to 2030 strategy, exemplify coordinated approaches to tackling these challenges.
Global partnerships play a pivotal role. The Pandemic Fund, established by the G20, has allocated billions to bolster healthcare infrastructure in low- and middle-income countries, such as Bhutan, Cambodia and more.
Regulatory agencies like the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) fast-track approvals for vaccines and therapies targeting epidemic-prone diseases.
Collaborative efforts, from genomic surveillance (for tracking pathogen mutations, helping to predict variants and guide vaccine updates) to climate change mitigation, have shown measurable success. Research shows how mosquito genetics, combined with expanding habitats due to climate change, may accelerate the risk of Zika virus outbreaks, emphasizing the urgency of targeted vector control strategies.
Similarly, the Global Influenza Surveillance and Response System (GISRS) has been pivotal in mitigating avian influenza outbreaks in Southeast Asia.
The WHO contained a Marburg virus outbreak in Tanzania in early 2024 with nine cases and six deaths. In Rwanda, 66 cases and 15 deaths have been reported, with no new cases since October 30, 2024. The 42-day countdown to declare the outbreak over has begun.
Lessons and Success Stories from 2023
The past year brought significant milestones in epidemic preparedness.
In 2023, vaccine-derived poliovirus cases in Afghanistan and Pakistan decreased by 33 percent compared to the previous year, showcasing the continued impact of robust community vaccination drives.
The COVAX initiative, focusing on equitable vaccine distribution, prioritized low-income countries, with 92 nations receiving over 1.6 billion doses through the Advance Market Commitment mechanism.
AI-driven platforms also proved invaluable. In India, AI-driven platforms, such as those developed by ARTPARK, forecasted dengue hotspots by analyzing environmental and epidemiological data, enabling targeted vector control measures in high-risk areas.
Across Africa, drone technology, which demonstrated scalable potential, mapped mosquito breeding sites, significantly reducing malaria transmission in high-risk areas.
Research and Innovation: Driving Progress
Groundbreaking research and innovative technologies reshaped epidemic preparedness in 2024.
Universal vaccines, such as a pan-coronavirus candidate in late-stage trials, aim to provide cross-protection against multiple strains. Another major advancement is the R21/Matrix-M malaria vaccine, recently prequalified by the WHO in December 2023. Developed by the University of Oxford and the Serum Institute of India, this vaccine has demonstrated high efficacy in preventing malaria in children and is expected to significantly reduce the disease burden in endemic regions.
Additionally, the RTS,S/AS01 malaria vaccine, the first to be prequalified by the WHO, continues to be deployed in African nations, protecting millions of children from malaria.
AI continues to play a growing role. Predictive models anticipate outbreaks of diseases like cholera, guiding preemptive public health measures.
Point-of-care diagnostics bring rapid, affordable testing to underserved areas, enabling timely interventions.
The WHO announced the first prequalification of a tuberculosis diagnostic test this month. This test, which enables the rapid detection of multi-drug-resistant tuberculosis, is expected to significantly improve early diagnosis rates globally.
Meanwhile, researchers advanced alternative therapies to combat antimicrobial resistance, targeting drug-resistant bacteria with novel antibiotics.
A promising area of research involves real-time wastewater monitoring, which has been pivotal in tracking outbreaks of diseases like polio and hepatitis.
Emerging Threats and Collective Actions
New challenges like drug-resistant tuberculosis, climate change and zoonotic spillovers demand urgent solutions. Global travel further accelerates disease spread, complicating containment efforts.
A Global Preparedness Monitoring Board (GPMB) report identifies 15 pandemic risk drivers across social, technological, environmental, economic and political dimensions. Cyber-attacks, misinformation and human-animal crossover risks exacerbate these threats. The report stresses the need for resilience through collaborative efforts, equitable health systems and cross-sectoral preparedness spanning human, animal and environmental health interfaces.
Governments can prioritize funding and surveillance while grassroots participation strengthens local response capacities. Actions like raising awareness, improving digital biosecurity and tailoring prevention strategies to local contexts are crucial. Local health workers trained to track and respond to outbreaks have also improved outcomes in vulnerable regions.
International Day of Epidemic Preparedness 2024 offers an opportunity for individuals, organizations and governments to take meaningful action.
Together, global and local collaboration can mitigate these emerging threats, ensuring preparedness is baked into future health responses.
