Honduras and Mexico face rising threats from screw-worm infestation

Honduras is experiencing a significant surge in screw-worm (myiasis) cases. Health authorities have recorded over 315 human cases, surpassing previous totals for 2025. The National Service of Agrifood Health and Safety (Senasa) has intensified its response, inspecting more than 950,000 animals and training approximately 49,000 producers to manage wounds and prevent the parasite's spread. Officials note that high temperatures and open wounds in livestock, pets, and humans facilitate the reproduction of the fly.

In Mexico, the situation remains critical in certain regions. Oaxaca has reported two human deaths due to advanced infections, while Veracruz has recorded two deaths and 110 confirmed human cases. Although livestock organizations suggest the plague is relatively controlled through producer training, the infestation has had severe economic consequences, including the suspension of cattle exports to the United States and significant market price fluctuations.

Health agencies in both nations are urging the public to maintain wound hygiene and seek immediate medical or veterinary attention if larvae are detected in wounds, mouths, or ears to prevent severe complications or death.
