Mexico reports surge in screw‑worm infestations affecting humans and cattle

Health officials in Veracruz's Orizaba city have recorded the first suspected human case of screw‑worm (gusano barrenador) infestation. The patient is under medical monitoring while laboratory tests confirm the presence of the larva. Authorities are treating all suspected individuals with preventive care as epidemiological investigations continue across several mountainous municipalities.

In Guerrero, local agrarian leader Evencio Romero Sotelo claimed up to 300 human miasis cases, with the parasite also affecting pets and an estimated 3,000 head of cattle. The outbreak has halted Mexican cattle exports to the United States, and officials cite the lack of a containment program and the earlier cessation of a sterile‑fly eradication effort as contributing factors. The situation raises concerns over public health, livestock productivity, and cross‑border trade.

Both regions emphasize improved wound hygiene and preventive measures during the rainy season as authorities work to contain the infestation.
