Summary of "The Economics of One Health" (Volume 2)

Core Content

This report explores the economic implications of implementing the One Health approach to address zoonotic and non-zoonotic diseases at the intersection of human, animal, and environmental health. It emphasizes the importance of interdisciplinary collaboration in disease prevention and control, particularly in the context of emerging and re-emerging diseases that can lead to pandemics and significant economic losses.

Main Viewpoints

• Zoonotic Diseases: These diseases, which can infect both animals and humans, account for 70% of emerging infectious diseases and have the potential to cause catastrophic global impacts.
• Economic Impact: The economic losses from six major zoonotic disease outbreaks between 1997 and 2009 amounted to at least $80 billion. Preventing these outbreaks could have yielded an average annual benefit of $6.7 billion.
• Cost of Pandemics: A severe influenza pandemic could lead to $3 trillion in economic losses and 71 million human fatalities, which is equivalent to 4.8% of the global GDP.
• One Health as a Solution: One Health is a collaborative approach involving multiple disciplines to achieve optimal health for people, animals, and the environment. It aims to reduce the gaps between institutions and disciplines that can lead to delays or failures in disease detection and control.
• Efficiency Gains: The report highlights that early and integrated disease control can lead to significant cost savings. For example, joint campaigns can reduce costs by sharing resources and reducing duplication.
• Effectiveness Gains: Better coordination between human, animal, and wildlife health services can lead to more effective disease control, as seen in case studies from Chad, India, Kyrgyzstan, and Canada.
• Cost-Benefit Analysis: Even when accounting for the low probability of pandemics, the benefits of investing in One Health systems far exceed the costs. The annual expected rate of return on investment ranges from 14% to 71%, depending on the level of pandemic prevention achieved.

Key Information

Zoonotic Disease Outbreaks and Their Impact

• Zoonotic diseases such as Nipah Virus, West Nile Fever, SARS, HPAI, BSE, and Rift Valley Fever have caused substantial economic and social disruptions.
• These diseases often originate in wildlife and spread to livestock and then to humans, highlighting the need for early intervention.

Economic Benefits of One Health

• The economic benefits of a global One Health system are substantial, with potential savings ranging from 10% to 15% of the total costs of disease control.
• The annual funding required to bring zoonotic disease prevention and control systems up to OIE and WHO standards ranges from $1.9 billion to $3.4 billion, depending on the level of disease prevalence risk.

Funding Allocation

• The report provides detailed analysis on the allocation of funding between the human and animal health sectors.
• It highlights the importance of integrating surveillance, diagnosis, and control efforts across sectors to reduce costs and improve effectiveness.

Global Preparedness

• The report suggests that the cost of implementing a One Health system is much lower than the potential losses from uncontrolled disease outbreaks.
• It emphasizes the need for a global, integrated approach to pandemic preparedness and disease control, which can provide a public good to the entire world.

Challenges and Gaps

• Data on disease control and prevention is limited, particularly for wildlife health services.
• There is a need for better data collection, analysis, and sharing across sectors and regions to improve preparedness and response capabilities.

Recommendations

• Transparency in Expenditure: Countries should record and provide public access to their expenditures on public health services, detailed by task and sector.
• Global Public Good: Control of zoonotic diseases is a global public good, and international cooperation and funding should be encouraged.
• Sustainable Funding Mechanisms: Sustainable funding mechanisms are essential for the long-term implementation of One Health systems.
• Policy Review: Governments and international agencies should review the estimated costs and benefits of One Health systems and consider further actions to increase investment in pandemic prevention.

Conclusion

The report underscores the critical role of the One Health approach in reducing the economic and social impacts of zoonotic diseases. It argues that investing in integrated systems for disease prevention and control is not only cost-effective but also essential for global health security and economic stability. The findings aim to stimulate further discussion and action on the economic aspects of One Health.
