What the Oct. 15 report shows
Epidemiological week 41 of 2026 has 42 cases of febrile rash illness and 2 confirmed measles cases, a preliminary figure. The report adds 3 lab-confirmed cases, one from Oaxaca and two from San Luis Potosí. It also includes one from Jalisco, confirmed under criteria set by the regional commission of the Pan American Health OrganizationPDF, the health agency for the Americas. That case dates from earlier weeks. No additional deaths were recorded.
Cases the directorate has just ruled on may have occurred in earlier weeks, so they are not recent infections. Since Sept. 4 it has warned that the daily count could rise as pending cases are classified, following the PAHO commission's visit in August.
By age, the groups with the most cases are 1 to 4 years (2 743), 5 to 9 years (2 416) and 25 to 29 years (2 255). Relative to their population, children under 1 are hit hardest: the directorate puts the rate at 101.72 cases per 100 000 inhabitants.
The PAHO count
PAHO's regional report No. 13, dated Oct. 8 with data through week 39, counts 13 595 confirmed cases and 23 deaths in Mexico in 2026. That figure cannot be compared with the ministry's total, which spans two years and has a different cutoff.
The ministry had not published a report after Oct. 15 by Monday morning, Oct. 19, and the document does not break down cases by vaccination status. The data cover the general population, with the highest incidence among infants under 1 and children 1 to 9.
