One Health is a concept that stresses the interconnectedness of human, animal, and environmental/ecosystem health and seeks an integrative approach to human and animal health issues. The concept provides a framework for examining complex health issues such as vector-borne and emerging infectious diseases, antimicrobial resistance, and food safety and security. In our globalized world, new approaches to preventing, treating, and controlling diseases are urgently needed as emerging diseases are increasing in frequency due to interconnected ecosystems and the close connections between humans and animals.
