Why One Health?
- Worldwide, nearly 75 percent of all emerging human infectious diseases in the past three decades originated in animals.
- Environmental health may affect human and animal health through contamination, pollution and poor conditions that may lead to new infectious agents.
- The world population is projected to grow from 7 billion in 2011 to 9 billion by 2050.
- To provide adequate healthcare, food and water for the growing global population, the health professions, and their related disciplines and institutions, must work together.
- The human-animal bond beneficially impacts the health of both people and animals.
