Overview
- Senasica’s latest update lists 86 confirmed screwworm infestations in Nuevo León across 17 municipalities, including a first case in Iturbide and higher counts in Aramberri, Linares, Doctor Arroyo and Montemorelos.
- The Nuevo León tally spans multiple species with 45 cattle, 16 dogs, 9 goats, 8 horses, 5 sheep and 3 pigs reported infected.
- Sonora launched a preventive simulation to rehearse rapid response and says the state remains free of the pest as it reinforces checkpoints, wound care protocols and epidemiologic surveillance with federal and ranching groups.
- Nationwide, Senasica reports 24,727 identified cases with 1,913 active, and notes the fly’s larvae eat live tissue in warm‑blooded animals and can infect people through open wounds.
- Querétaro has logged 324 cases since November 2024 with 68 active, while veterinarians urge pet owners to keep wounds clean, seek prompt care for suspected myiasis and avoid home remedies like lime or oil.
