This course focuses on developing a critical understanding of the One Health approach and its relevance to Global Health, exploring its application to emerging and re-emerging infectious diseases, antimicrobial resistance, food safety and security, vector-borne diseases, and environmental and climate-related health risks. It also examines the challenges of implementing One Health in low- and middle-income or resource-limited settings, and critically discusses the role of global organisations such as WHO, FAO, WOAH, and UNEP in advancing One Health initiatives.

1. Introduction to One Health

• Definition and concepts related to One Health
• Human-animal-environment interactions

2. Epidemiology and Disease Surveillance

• Transmission dynamics between animals and humans
• Risk assessment and control strategies
• Role of wildlife and livestock in disease spread

3. Infectious diseases and One Health

• Drivers of emerging diseases (climate change, urbanisation, deforestation)
• Pandemic preparedness
• Global and local surveillance

4. Antimicrobial Resistance (AMR) in a One Health context

• AMR in human and veterinary medicine
• Antibiotic use in agriculture
• Environmental factors related to AMR
• Policy and stewardship approaches

5. Environmental health and ecosystem approaches

• Impact of environmental degradation on health
• Wildlife conservation and disease prevention
• Climate change and vector borne diseases

6. Food safety and security

• Zoonotic pathogens in food chains
• Veterinary public health
• Global food safety regulations

7. Policy, governance and implementation

8. Group work – Case study: Applying One Health concepts to Global Health problems, presentation to the class will be graded

By the end of this course, participants will be able to:

1. Critically define the One Health approach and explain its relevance to Global Health

2. Analyse how the One Health approach can be applied to:

• Emerging and re-emerging infectious diseases
• Antimicrobial resistance (AMR)
• Food safety and security
• Vector-borne diseases
• Environmental and climate-related health risks

3. Identify gaps and challenges in applying One Health approaches in low- and middle income and /or resource settings

4. Critically discuss the role of global organisations (WHO, FAO, WOAH, UNEP, etc.) in One Health
