Overview
- Active cases fell from 1,145 on December 10 to 492 by January 7, while cumulative reports rose to 13,335, with roughly 96% of active events located across nine southern and Gulf states.
- Authorities list four states now cleared after earlier detections (Jalisco, Morelos, Nuevo León, Querétaro) and report fewer than 10 cases under control in Tamaulipas, Michoacán, San Luis Potosí and the State of Mexico.
- Senasica launched an emergency plan in Tamaulipas and northern Veracruz featuring intensified field surveillance, focal sterile‑fly releases, stricter movement controls and a temporary halt on shipments from affected zones to Nuevo León feedlots.
- Construction of the Metapa, Chiapas sterile‑fly plant is 48% complete with a target to reach 200 million sterile insects weekly in the first half of 2026 to scale biological suppression.
- Economic strain persists as analysts estimate about $1.3 billion in lost export revenue and over one million head withheld; northern producer groups say they can guarantee safe transit to the U.S. and argue border reopening hinges on commercial negotiations.
