  • Focus on early identification of pathogens capable of spilling over from animals; extensive global collaboration to mitigate future pandemics.

• Achievements:

  • Discovery of numerous novel coronaviruses and training health workers globally to combat outbreaks.

• Expansion of Projects:

  • Continuation of efforts to prevent pandemics through surveillance and proactive health measures.

Page 7: Logistics of Spillover Surveillance

• Mapping Hotspots:

  • Utilizing scientific methods to identify potential spillover areas; collaboration with local governments for effective implementation.

• Community Involvement:

  • Importance of engaging with communities for successful risks mapping and safety measures.

• Sampling Strategies:

  • Biosafety measures in place to ensure safe sampling of wildlife; need for ethical approvals for studies involving animals and humans.

• Laboratory Capabilities:

  • Strengthening local laboratory infrastructure for wildlife virology essential for effective disease detection.

Page 8: Handling Identified Pathogens

• Outbreak Investigation Protocol:

  • Collaboration with government authorities when dangerous pathogens are identified; ethical considerations for data sharing.

• Example Case:

  • Novel Ebola virus discovered; practical measures followed to educate communities on safety measures.

• Information Dissemination:

  • Challenges in balancing timely information sharing with the integrity of the scientific process.

Page 9: Hotspot Identification

• Defining Hotspots:

  • Areas with high biodiversity and human-wildlife interactions identified as spillover hotspots.

• Patterns of Spillover Events:

  • Increased risk correlates with landscape changes; highlights need for conservation of wildlife and habitats.

Page 10: Spillover Mechanisms

• Understanding Spillover Events:

  • Key pathways include wildlife market interactions and direct human contact with animals.

  • Ecosystem Disruption:

  • Human-induced changes increase risk; people often exposed to diseases their bodies are not immune to.

Page 11: Future Prevention Strategies

• Current Evidence for SARS-CoV-2 Origin:

  • Believed to be of bat origin; uncertainty exists regarding intermediate hosts.

• Proactive Disease Monitoring:

  • Importance of being prepared and monitoring systems for emergent pathogens requires attention beyond human cases.

• Past Oversight:

  • Increased awareness of the need for better mechanisms for early detection and response in future pandemics.

Page 12: Collaborative Responses

• Implementing One Health Approaches:

  • Successful responses require multi-disciplinary collaboration; using existing structures like Uganda's zoonotic disease task force.

• Public Health Response:

  • Encouragement for better preparedness and rapid activation of health task forces in the future.

Page 13: Conservation and Wildlife Conflict

• Conservation Impacts on Public Health:

  • Need for conservation measures to consider cultural and nutritional needs of at-risk communities.

• Reducing Spillover Threats:

  • Addressing illegal wildlife trade supports both public health and wildlife conservation efforts.

Page 14: Opportunities for Improvement

• Post-Tragedy Learning:

  • Urgency in addressing human behavior and investing in preventative measures to avoid future pandemics.

• Proactive Resource Allocation:

  • Need for societies to prioritize funding for proactive measures rather than reactive responses to pandemics.

Page 15: Five Key Takeaways

• Spillover Events:

  • Rising occurrence of new infectious diseases; need for vigilance in monitoring for early detection.

• Data Sharing Ethics:

  • Importance of quickly informing communities at risk rather than waiting for peer-reviewed publications.

• Human Impact:

  • Recognizing human impact on spillover events and adjusting conservation and public health policy accordingly.

• Future Preparedness:

  • Investing in global health infrastructure is critical for prevention efforts moving forward.

• Interdisciplinary Collaboration:

  • Emphasizing need for teamwork across fields to comprehensively address health impacts of zoonotic diseases.
