Which criterion describes the ability to control or manipulate how the disease spreads?

• A. Small host range
• B. Acceptability to industry
• C. Single or limited spectrum of disseminating mechanisms that can be manipulated
• D. Effective diagnostic test for ID of carriers

Answer: (C)

The main idea here is how easily disease spread can be controlled by targeting its transmission pathways. When there is a single or limited set of dissemination mechanisms that can be manipulated, public health actions can focus on disrupting those specific routes, making it feasible to prevent or slow spread. This makes the agent easier to control in practice.

Having a small host range might limit spread but doesn’t address how spread itself can be manipulated. Acceptability to industry is about practicality rather than control of transmission. A good diagnostic test helps find carriers, which aids detection but doesn’t by itself describe how to intervene to stop transmission.
