The Mexican state of Sonora is working to vaccinate its population against measles, as cases of the disease rise around the country.
Mexican officials say 29 people have died of measles in the country since the beginning of last year, and authorities are urging vaccinations.
The state of Sonora, which borders Arizona, has confirmed 166 cases and one death since the beginning of 2025. That puts it within the top 10 of Mexico’s 31 states for measles cases over the past year.
But that number is dwarfed by the neighboring state of Chihuahua, which borders Texas and New Mexico, where more than 4,000 measles cases were confirmed over the past year — largely centered around that state’s Mennonite community.
Mexico’s president said almost 1.7 million measles vaccinations were given across the country last week, and her government’s goal is to vaccinate 2.5 million people weekly.
In Sonora, the state government is holding measles vaccination clinics in various neighborhoods around the state capital, Hermosillo, as well neighboring towns and cities.
