Why one health?

• One Health was launched to recognition of threats to people posed by the emergence of animal diseases such as HPAI, which has the capacity to become pandemic and kill vast numbers of people (and poultry).
• For that reason, an early focus of One Health was dominated by concerns primarily for human health and secondarily for animal health as advanced by physicians and veterinarians.
• In 2010, a Tripartite Agreement signed by the Food and Agriculture Organization of the United Nations (FAO), World Health Organization (WHO), and the World Organization for Animal Health (OIE).
• This agreement promotes cross-sectoral collaboration to address and reduce risks from zoonosis and other public health threats existing and emerging at the human-other animal ecosystems interface.
