Which facility design measure best reduces pathogen transmission by creating physical barriers between animals and visitors?

• A. Signage informing visitors about risks
• B. Storage area for strollers
• C. Maintaining barriers between animals and visitors
• D. Clean up soiled bedding promptly

Answer: (C)

Creating physical barriers between animals and people is an engineering control that stops transmission at its source by preventing direct contact, limiting droplet spread, and reducing contamination of surfaces. In facility design, solid barriers such as glass panels, fences, or enclosed viewing areas establish a protected zone where visitors cannot touch animals or shared surfaces, dramatically lowering the chance that pathogens move from animals to humans. This is more effective than signage, which informs but does not prevent exposure, or housekeeping actions like promptly cleaning bedding, which reduce contamination after contact but don’t block exposure in the first place. By keeping animals and visitors physically separated, the risk of multiple transmission routes is minimized while still allowing safe, supervised interaction where appropriate.
