One health definition:
One Health is a collaborative, multi-sectoral, and trans-disciplinary approach, working locally, regionally, nationally, and globally, to achieve optimal health and well-being of all animals, people, plants and their shared environment, recognizing their inextricable interconnections.
In order to effectively identify, respond and prevent the emergence and spread of zoonoses and food safety issues, epidemiological data and information from laboratories should be shared among different sectors. Government officials, researchers and workers in different sectors at the local, national, regional and global levels should conduct a joint response to any health threat.
Here are a few areas that urgently need the One Health approach, at all levels of academia, government, industry, policy and research,  because of the inextricable interconnectedness of animal, environmental, human and plant health.
