New World Screwworm (NWS) Awareness for Veterinarians
The Department of Agriculture, Trade and Consumer Protection (DATCP) is providing current information about New World Screwworm (NWS), Cochliomyia hominivorax, a parasitic insect that poses risks to both animals and humans. Given the recent detection of NWS in Chiapas, Mexico, it is important for Wisconsin veterinarians to stay informed.
What is New World Screwworm?
NWS is a fly larvae that infests the living tissue of warm-blooded animals, including livestock, pets, wildlife, and occasionally humans. The larvae/maggots burrow into the flesh of the host, causing severe damage and potentially fatal infections.
Why Should Veterinarians Be Concerned?
With recent detections of NWS in Mexico and its northward spread, it is crucial for all veterinarians to be aware of the risks. Animals transported into Wisconsin or those involved in holiday travel to warmer climates (e.g., Central/South America, the Caribbean) are at higher risk.
Key Points to Remember:
-
Check for Signs: Look for draining or enlarging wounds, signs of discomfort, and the presence of maggots or eggs.
-
Report Suspected Cases: NWS is a reportable disease. If an animal is suspected to be infected, contact DATCP immediately: DATCP Home Animal Diseases
-
Travel Precautions: Ensure pets traveling internationally are inspected for NWS.
