Guadalajara

Epidemiological Brief

Guadalajara faces a high measles burden, driven by Mexico's national outbreak—the largest active outbreak in the Western Hemisphere. Jalisco state is estimated to have reported 89 new measles cases in EW19 (804 cumulative YTD), based on the PAHO Situation Report 3 national total of 10,049 cases through EW19 and DGE historical state-level distribution. These are modelled estimates; the DGE state-level breakdown is pending resolution of a scheduled site maintenance period. The normalized measles signal is 66.4/100. The composite Santé score is 66.4 (medium), the highest among the three Mexican host cities except Mexico City. Jalisco's substantial tourist infrastructure and international connectivity present significant conditions for measles amplification and export. Akron Stadium and fan zones in metropolitan Guadalajara should implement mandatory two-dose MMR verification for venue staff. Mobile vaccination units should be positioned at fan villages. International health authorities should issue travel health advisories for unvaccinated individuals planning attendance. Active case reporting to PAHO is essential. Sante Index v0 is a watching signal, not a forecast.
