The One Health approach : what is the role of environmental health?

When and Where

Hélène Carabin


The concept of One Health has been around for centuries, but the official term was adopted in 2004. Despite its devastation for human health, the COVID-19 pandemic had the advantage of raising awareness regarding the One Health approach globally. A “One Health High Level Expert Panel” (OHHLEP) was launched in June 2021 – the OHHLEP proposed a definition for the One Health approach on Dec 1 2021, at the same time as a special World Health Assembly session was taking place to initiate discussions about a potential pandemic treaty. In April 2022, the World Health Organization, the World Organization for Animal Health, the Food and Agriculture Organization and the United National Environment Programme signed a memorandum of understanding to form a quadripartite to tackle One Health challenges through a legal agreement. In this seminar, I will present the various health issues where the One Health approach is relevant with an emphasis on the role of the “environment” component of One Health.
