PurposeReduce Spread to Non-infested animals and prevent NWS from establishing in new areas. DefinitionsInfested Zone (IZ) Zone that immediately surrounds 1) a premises with an infested domestic animal, 2) the location of infested wildlife, or 3) the location of NWS fly detections.Perimeter should be at least 20 km (~12.43 miles) beyond the perimeter or location of infested animals (domestic or wildlife) or NWS fly detections. This zone may expand with additional NWS detections based on epidemiological circumstances. Adjacent Surveillance Zone (ASZ) Zone that immediately surrounds an IZ.An ASZ may initially be established to surround an NWS isolated* or suspect case if it is located outside an established IZ and 1) it has a travel history outside the United States to a screwworm-infested country within the previous 10 days, 2) early case detection/treatment prevented larval development in the area as demonstrated through surveillance, or 3) is a suspect case that is not available to be sampled, such as suspect wildlife based on wildlife camera images. However, an IZ should immediately be established anytime NWS establishment is suspected.Perimeter should be 20 km (~12.43 miles) beyond the perimeter of the IZ. The size of the ASZ is maintained at a 20 km perimeter when the IZ expands. Fly Surveillance Area (FSA) Area that overlaps the IZ and ASZ and extends outward from an NWS detection based on fly habitat and geographic range.Between 0 to 200 km (~124.27 miles) from infested animals (domestic or wildlife) or NWS fly detections. The FSA border may not extend equally in all directions as its sizing is based on assessment of suitable habitat and the geographic range of flies for the area. *An NWS isolated case is a confirmed infestation that is contained to the initial finding, such as a single animal or person, and does not indicate a wider, self-sustaining NWS pest population in the area. The case must have a history of movement from an Infested Zone or a country recognized as affected with NWS to be designated as an NWS isolated case.
