The One Health Integration Working Group (formerly Integrating Animal Services with Public Health Working Group) has expanded the scope of our work to include considerations of One Health (the interconnectedness of the health of humans, animals, and the environment). Our group is focused on three areas: drafting a toolkit for integrating animals services with human and environmental service providers, discussing the practical implications for implementing One Health considerations in HASS programs, and developing a rigorous research agenda that can assess the One Health impacts of HASS programs, when implemented.
