The dashboard below is designed to provide a current snapshot of confirmed New World screwworm animal and wild fly detections in the United States. USDA APHIS is fully prepared to respond to detections, and we work closely with our State partners on surveillance, reporting, and control efforts.
The dashboard captures individual animal cases by county and state, animal type and species, confirmation date, and status.
- Active animal cases are those that involve ongoing disease mitigation efforts on the individual animal until it is free of NWS myiasis, including treatment and wound management of the infested animal.
- Inactive animal cases refer to situations where mitigation activities are no longer required on that animal. Either the animal has fully recovered, with myiasis resolved and treatment completed, or appropriate measures have been taken to prevent the spread of NWS, such as appropriate carcass management of a deceased infested animal.
NOTE: While individual animal cases may be changed to an inactive status, there may still be active infested zones in those areas until additional conditions are met for infested zone release. Please see the individual state websites to view active infested and surveillance zones or contact the State Animal Health Official’s office directly to confirm zone status.
The dashboard also captures fly traps with at least one NWS wild fly detected by county/State and confirmation date.
This dashboard is not intended to support international trade. Additional surveillance for international and bilateral trading partners may be necessary both prior to and after the release of the Infested Zone.
