Jalisco Measles Outbreak Spikes With 667 New Cases One Week After Civil Unrest in Mexico

Just days after a wave of civil unrest erupted in Jalisco, the western Mexican state is facing a significant outbreak of measles.

In the past week, Jalisco has reported 667 new confirmed measles cases, raising the cumulative total for February from 1,995 to 2,662, according to the latest data from the Mexican Ministry of Health (MOH).

This sharp increase in late February 2026 highlights Jalisco's critical role in the national epidemic.

In response to this health crisis, MOH measures in Jalisco have intensified following the brief but intense period of civil unrest.

Mobile vaccination teams have been deployed to affected urban and rural areas, and authorities are urging residents to check their immunization records. Free measles, mumps, and rubella vaccines are available at public health centers.

Since the beginning of 2026, Mexico has recorded 4,497 confirmed measles cases nationwide, with Jalisco accounting for 59% of the total. Health officials attribute the spread of the disease to gaps in vaccination coverage in densely populated areas, exacerbated by recent disruptions to the healthcare system in cities like Guadalajara and Puerto Vallarta.

According to the U.S. Embassy in Mexico, all restrictions for U.S. government staff related to the events of February 22, 2026, have been lifted.

"We have no reports of road closures directed by local authorities," the Embassy stated in a travel alert posted on February 25, 2026. "U.S. citizens in Mexico should resume standard precautions."

"While flight schedules have returned to normal, if your direct flight to the United States is canceled, consider booking a connecting flight through another Mexican or U.S. city," added the Embassy.
