| The main surveillance objective for a component can, sometimes, be different from the overall main objective of the system, although the component will also contribute to the system objective.\\ \\ | The main surveillance objective for a component can, sometimes, be different from the overall main objective of the system, although the component will also contribute to the system objective.\\ \\ | ||

| Surveillance designers should consider other sectors/strata from the total susceptible population (defined in the surveillance scenario) which are not being covered by this particular component and list them, to later compare to sectors covered by other components. For example, if a surveillance system targets cattle and the current surveillance component addresses only dairy cattle, then part of the susceptible population is being missed, namely beef cattle and veal calves.\\ \\ | Surveillance designers should consider other sectors/strata from the total susceptible population (defined in the surveillance scenario) which are not being covered by this particular component and list them, to later compare to sectors covered by other components.

| ===== 3.6 Target criteria ===== | ===== 3.6 Target criteria ===== | ||
| This refers to whether there were any selection criteria used to choose this particular target population (if the target population for this component is not the entire susceptible population defined for the surveillance system). Criteria for selection could be for instance **logistic/convenience** (this component focuses on a particular sector of the population because they are easier to sample or more accessible); **higher probability of infection**; **higher probability of showing clinical signs**; **feasibility of detection** (the diagnostic tests available can only be used in animals above a certain age, or non-vaccinated animals); or higher severity of **consequences** in case of infection, which is the case for instance when surveillance is focused on breeder animals.\\ \\ | This refers to whether there were any selection criteria used to choose this particular target population (if the target population for this component is not the entire susceptible population defined for the surveillance system).
