Today, 3 November 2021, marks the sixth annual One Health Day, a global campaign that celebrates and brings attention to the need for a One Health approach to address health threats at the human-animal-environment interface.

One Health is a collaborative, multisectoral and transdisciplinary paradigm for framing complex public health issues. Applying its approaches, which recognize the interconnection between people, animals and their shared environment contributes to improvements in animal, human and environmental health. One Health approach plays a critical role in the context of the global COVID-19 outbreak to prevent the next pandemic.

The International Livestock Research Institute (ILRI) and its partners are using the One Health approach to tackle agriculture-associated risks. They are doing this by promoting and facilitating transdisciplinary partnerships to manage zoonotic and food-borne diseases, improve food safety, and reduce antimicrobial resistance (AMR) through the generation and use of knowledge, technologies and products in low-and-middle-income countries (LMICs) of East and Southeast Asia including Cambodia, Laos and Vietnam.

We celebrate this year’s One Health Day by featuring a selection of the ILRI East and Southeast Asia regional office’s recent research outputs on this topic.

Earlier this year, ILRI joined 32 national and international partners in the second phase of the framework for One Health Partnership for Zoonoses (OHP), which was officially launched in Hanoi on 23 March 2021 to strengthen ongoing work in the control of zoonotic diseases, or diseases transmitted from animals to humans, in Vietnam. This initiative by the Vietnamese government will run from 2021 to 2025.

In August, ILRI and other CGIAR centres convened a series of online consultative meetings with research collaborators to gain insights on the main One Health priorities, challenges, interventions and partner organizations in Vietnam for the Protecting human health through a One Health approach initiative. Once approved, the CGIAR One Health initiative will start in January 2022 and run for an initial three years.
