Overview

• The federal tally lists 4,353 confirmed infections and 17 fatalities, with Chihuahua accounting for 4,051 cases and smaller counts in Sonora (87), Coahuila (53), Guerrero (35) and six in Mexico City.
• Nearly six million doses were administered between January 1 and August 29 as officials push two‑dose coverage beyond the current 81.1% toward a 95% goal.
• Outbreak protocols widen eligibility to a dose‑zero for infants 6–11 months, routine shots at 12 and 18 months, two doses for children 2–9 with incomplete schedules, and vaccination for ages 10–49 plus health, education and agricultural workers.
• Active case response includes epidemiological sweeps within a 25‑block radius of each confirmed patient, with the 079 line guiding residents to nearby vaccination sites.
• Local operations ramp up: Mexico City’s SR/SRP campaign uses fixed posts, mobile kiosks and house‑to‑house brigades with 131,432 doses since October 2024, while Chihuahua deploys the Escudo Juárez strategy to offer free shots up to age 49.
