Which of the following is NOT listed as a barrier to effective One Health?

• A. Public Awareness
• B. Legal Authority
• C. Funding
• D. Information Technology

Answer: (A)

One Health relies on coordinated actions across human, animal, and environmental health sectors, so the barriers that most often block effective implementation are those that limit resources, authority, and information flow. Funding is essential to run programs, staff, and activities across sectors; without it, efforts stall. Legal authority matters because cross-agency collaboration and data sharing often require formalmandates or powers to compel cooperation and enforce standards. Information technology is crucial for exchanging data and ensuring systems can talk to each other across disciplines; without interoperable IT, a true shared understanding and rapid response across sectors isn’t feasible.

Public awareness, while important, isn’t typically listed as a structural barrier to effective One Health. It serves as a facilitator—raising support, understanding, and engagement among the public and stakeholders. If awareness is low, there’s room for targeted outreach to improve buy-in, but that doesn’t in itself block the fundamental ability to implement One Health activities the way funding, legal authority, and IT do.
