Mexico-Spain mosquito control efforts

In early August 2026, Mexico’s federal and state health secretariats rolled out a wide‑ranging set of preventive actions against zoonotic and food‑borne threats. Measures included warnings about the livestock‑infesting Gusano Barrenador in Chihuahua, vector‑control campaigns against dengue‑carrying Aedes aegypti in the Mexico City metro area, food‑handling guidelines in Querétaro, gastrointestinal disease outreach in Coahuila, and the expansion of free primary‑care services in Aguascalientes.

A few days later, the focus narrowed to mosquito control. In Hidalgo, Mexico, the National Water Commission conducted fumigation around the Rojo Gómez reservoir, coordinated with the National Center for Preventive Programs and Disease Control. Simultaneously, Don Benito, Spain, approved a municipal vector‑surveillance plan targeting West Nile virus, employing larvicides, adult mosquito control, and promotion of natural predators. Both initiatives underscore a coordinated, multi‑level effort to curb vector‑borne diseases in the region.
