Overview
- Mexico has confirmed 7,417 measles cases and 26 deaths through January 23, with 107 new cases in the prior 24 hours and transmission reported in all 32 states and 265 municipalities.
- Jalisco and Chiapas show the sharpest recent increases in 2026, while Chihuahua remains the largest cumulative hotspot with 4,493 cases and 21 deaths but few new cases this year.
- Authorities report 987 cases so far in 2026, and Mexico continues free vaccination at IMSS, ISSSTE and public clinics after securing 27.3 million doses for the year.
- The response includes a ‘dose zero’ for infants 6–11 months and guidance for unvaccinated or incompletely vaccinated adults—especially those aged 20–39—as well as health, education and agricultural workers.
- Jalisco is conducting door‑to‑door ‘block’ vaccinations around confirmed cases, and Baja California is targeting agricultural areas after 26 cases were detected, mostly linked to worker mobility from other states.
