What is the purpose of traffic flow planning in ICRA?

• A. To prevent unnecessary movement into clean areas.
• B. To maximize patient traffic through zones.
• C. To ignore staff movement.
• D. To allow random movement.

Answer: (A)

Traffic flow planning in ICRA focuses on controlling how people and materials move through spaces to reduce the spread of infection. The goal is to protect clean areas by limiting movement that isn’t essential, so pathogens are less likely to be carried from dirty or contaminated zones into sterile or high-cleanliness areas. Designing routes, entry and exit points, and the sequencing of movements helps ensure that staff, patients, and supplies travel in a way that minimizes cross-contamination and unnecessary traffic into protected zones. Maximizing patient traffic or allowing random movement would increase contamination risk, and ignoring staff movement would ignore a major source of transmission.
