Lecture Notes: Global Catastrophe Preparedness
Introduction
Historical Concerns
Past worry: Nuclear war.
Preparation: Storing food and water in barrels for survival.
Current Concern
Risk of global catastrophe now: Highly infectious virus over nuclear war.
Greater investment has been made in nuclear deterrents than in epidemic prevention systems.
Epidemic Preparedness
Lack of Preparedness
Example: Ebola outbreak.
No structured system was in place for dealing with epidemics.
Key Missing Pieces
No ready group of epidemiologists.
Lack of accurate and timely case reporting.
Insufficient medical teams and volunteer orchestration.
No one to explore treatment approaches or diagnostics.
Ebola Case Study
Ebola Outbreak Observations
About 10,000 deaths, mainly in West Africa.
Factors preventing wider spread:
Heroic work by health workers.
Ebola’s nature (not airborne, symptoms visible when contagious).
Luck in not reaching urban areas.
Future Risks
Potential Viral Threats
Future viruses might spread more easily, e.g., through air or bioterrorism.
Example: Spanish Flu killed over 30 million people.
Importance of Preparation
Preparedness can reduce potential harm substantially.
Building a Response System
Tools and Technology
Use of cell phones and satellites for information flow and tracking.
Advances in biology for rapid pathogen response.
Response System Components
Strong health systems in poor countries for early outbreak detection.
Medical reserve corps with trained personnel.
Partnership of medical personnel with military for logistics and area security.
Simulation and Research
Simulations ("Germ Games")
Essential for identifying and addressing preparedness gaps.
Last germ simulation in the US was in 2001 and was not successful.
Research and Development
Need for advanced R&D in vaccines and diagnostics.
Example: Adeno-associated virus as a quick response tool.
Economic Perspective
Cost and Benefit Analysis
Modest cost compared to the potential global harm of a pandemic.
World Bank estimates a flu pandemic could reduce global wealth by over three trillion dollars and cause millions of deaths.
Investments would also improve global health equity and safety.
Conclusion
Call to Action
Importance of beginning preparations now to be ready for future epidemics.
Lessons from Ebola should act as a wake-up call.
Preparedness should be a global priority.
