Abstract

Emerging infectious diseases (EIDs) pose significant threats to global public health, economic stability, and environmental sustainability. Approximately 75% of emerging infectious diseases affecting humans originate from animals. The interconnectedness of human, animal, and environmental health necessitates a multidisciplinary framework known as the One Health approach.

Objective

This study evaluates the effectiveness of the One Health approach in addressing emerging infectious diseases by integrating surveillance, prevention, preparedness, and response strategies across human, animal, and environmental sectors.

Methods

A multicenter mixed-methods study was conducted using epidemiological data from zoonotic disease outbreaks reported between 2015 and 2025. Data from public health agencies, veterinary services, environmental monitoring systems, and international organizations were analyzed to assess disease trends, surveillance efficiency, and outbreak response effectiveness.

Results

Integrated One Health programs demonstrated earlier outbreak detection, improved intersectoral collaboration, and reduced disease transmission rates. Countries implementing comprehensive One Health strategies showed a 42% improvement in outbreak response time and a 35% reduction in disease spread compared with traditional sector-specific approaches.

Conclusion

The One Health approach provides a comprehensive framework for addressing emerging infectious diseases. Strengthening collaboration among healthcare professionals, veterinarians, environmental scientists, and policymakers is essential for future pandemic preparedness and global health security.
