The World Organisation for Animal Health (WOAH) acknowledges the continuous spread of New World screwworm (NWS) (Cochliomyia hominivorax) in the Americas. Since its resurgence in Central America, first notified by Panama in June 2023, the disease has now been reported in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Mexico, with more than 20, 000 new outbreaks reported in the World Animal Health Information System (WAHIS).   

The prevention and control of this parasitic zoonotic disease that poses a serious threat to animals, humans, and the environment, is challenging and requires long-term coordinated efforts by affected and at-risk countries. Recognising this need, and acknowledging the ongoing work undertaken by countries and regional partners, the Global Framework for Progressive Control of Transboundary Animal Diseases
(GF-TADs)   mechanism has been mobilised in the Americas through a standing group of experts on screwworm   to facilitate experience and knowledge sharing between experts, Veterinary Services, other national authorities, and international organisations, and formulate tailored recommendations for prevention and control. Regional partners of GF-TADs are working actively to strengthen the capacities of our Members both affected and at risk, ensuring that Veterinary Services are equipped to detect, contain, and respond swiftly and effectively to outbreaks.
