One Health, a concept familiar to veterinarians, is the idea of an intrinsic interconnection between human, animal and environmental health. When one sector is sick, the other two are impacted as well. Therefore it makes sense to think about "preventative health care" more holistically in terms of all three domains.
In recent years, with climate change and the occurrence events like the COVID 19 pandemic, the idea of One Health has become more apparent to the general public, although those terms may not be used.
As documented by the Centers for Disease Control and Prevention, more than 70 percent of all known infectious diseases, and 65 percent of newly emerging infectious diseases, are zoonotic, meaning they can be transmitted from animals to people. Therefore, strategically it makes sense to figure out ways to prevent the next pandemic and protect human and animal health by stopping zoonotic diseases in the animal population before it gets to the human population. Holistic interventions with this objective will involve environmental mitigation and protection to be effective and sustainable.
