Dear Colleagues,

The study of One Health addresses complex global challenges arising from interactions between human, animal, and environmental health. These domains have become increasingly apparent in the face of emerging infectious diseases and environmental degradation.

Zoonotic diseases, crossing the species barrier from animals to humans, strongly support the need for a One Health perspective. Diseases like Ebola, SARS, and COVID-19 have originated in animals and crossed species barriers to cause human health crises. Additionally, the increasing emergence of antimicrobial resistance (AMR) has typically been accredited to the overuse of antibiotics in human health settings. However, following a One Health approach, AMR can be linked to veterinary antimicrobial use, from livestock farming to the movement of AMR through the environment. By studying One Health topics, factors contributing to the emergence of such diseases and infections can be identified and strategies can be developed to aid in their prevention and control.

Environmental changes, driven by human activities, also influence health outcomes. Climate change, deforestation, and pollution both impact human and animal health, affecting the availability of resources, altering disease patterns, and threatening biodiversity. A One Health approach allows for a comprehensive understanding of interconnected relationships between humans, animals, and the environment, supporting the development of sustainable solutions.

Furthermore, the intensification of agriculture and globalisation has increased the risk of disease spread. Livestock farming practices can lead to the emergence of antimicrobial resistance, posing a threat to both animal and human health. One Health research is essential for developing responsible agricultural practices, preserving biodiversity, and ensuring food security.
