Which statement best describes ecohealth in relation to One Health?

• A. Ecohealth emphasizes ecosystem approaches to health in economic terms.
• B. Ecohealth is a subset of microbiology focusing on environmental pathogens.
• C. Ecohealth addresses only climate factors.
• D. Ecohealth emphasizes ecosystem approaches to health and well-being, aligning with One Health's cross-sector focus.

Answer: (D)

Ecohealth centers on how ecosystems shape health and well-being and uses approaches that involve multiple sectors and disciplines. This fits One Health by emphasizing connections across human, animal, and environmental health and promoting cross-sector collaboration to improve health outcomes.

The best statement captures this broad, integrative focus: ecosystem approaches to health and well-being, aligning with One Health's cross-sector focus.

The other descriptions narrow ecohealth too much or miss its scope entirely. Focusing on economics misses the broader health and ecological relationships. Viewing ecohealth as a microbiology subset overlooks its interdisciplinary nature that includes environment, society, and governance. Limiting it to climate factors ignores biodiversity, land use, pollution, social determinants, and actions across sectors that influence health.
