Final answer:
Option 'a', the ability to accommodate 3 to 5 million persons, is not a feature of a control center, which is essentially operational rather than residential. It should instead provide operational support, data aggregation, regional integration, and constant availability for emergency management.
Step-by-step explanation:
The question pertains to the characteristics of a control center that would typically be a part of a health emergency management system such as those found at the Centers for Disease Control and Prevention (CDC). Considering the provided reference to the CDC command and control centers, which are designed to monitor and respond to health threats by aggregating data and coordinating actions, we can deduce the features of an effective control center. Feature 'a', the capacity to accommodate 3 to 5 million persons, is not characteristic of physical control centers, such as those for disease monitoring and emergency management, as their purpose is not to house a population but to serve as operational hubs for information management and response coordination.
Control centers should contain aggregated data for an Essential Electronic Health Record (EHR) (option 'b') and have linkages to other centers to facilitate continuity of care across different regions (option 'e'). They also need to be available 24/7 (option 'd') to react to emergencies at any time. However, contrary to option 'c', a control center, especially in the context of disease outbreak management, is usually integrated within the region it serves to facilitate timely and locally relevant responses, rather than being external. Therefore, option 'a' is the correct answer as it does not describe a typical feature of a control center.
