One Health involves collaboration across disciplines at which levels?

• A. Local
• B. National
• C. Global
• D. All of the above

Answer: (D)

One Health is about coordinated action across human health, animal health, and the environment, and this collaboration happens at every scale where health decisions are made. At the local level, clinicians, veterinarians, public health workers, and communities work together to detect outbreaks, manage zoonotic risks, and monitor environmental factors that affect health. At the national level, government agencies integrate data across sectors, align policies, and allocate resources to surveillance, prevention, and response programs. At the global level, international organizations share data, set standards, and coordinate responses to threats that cross borders. Threats like emerging zoonoses and antimicrobial resistance don’t respect boundaries, so addressing them effectively requires input and action from local, national, and global actors. That’s why the best answer is that One Health involves collaboration across all these levels.
