Overview

• Health officials reported 4,353 confirmed cases and 17 deaths, with 4,051 infections in Chihuahua; Sonora (87), Coahuila (53) and Guerrero (35) follow at much lower levels.
• Between January 1 and August 29, 5,980,779 measles vaccine doses were administered nationwide and catch‑up efforts in six‑year‑olds recovered about 92% of missed schedules.
• When a case is found, teams activate surveillance across a 25‑block radius, investigate within 48 hours, vaccinate close contacts within 48–72 hours and monitor contacts for 30 days.
• Outbreak guidance includes a dose zero at 6–11 months, routine doses at 12 and 18 months, two doses for ages 2–9 with incomplete schemes, and vaccination for ages 10–49 and priority workers; doses are free and the 079 line helps locate sites.
• Mexico City’s Operativo SR/SRP deploys fixed posts, mobile kiosks and door‑to‑door brigades, and a National Week of Public Health will run September 6–13 to intensify outreach.
