A measles outbreak has been confirmed in a county detention facility in Luna County, New Mexico, where five inmates tested positive for the virus. The New Mexico Department of Health is investigating the situation, and federal officials have reported an additional 13 cases. The outbreak is part of a broader resurgence of measles across the Americas, with cases rising 29-fold compared to the previous year, according to the Pan American Health Organization (PAHO). In the United States, new cases have been reported in several states including Wyoming, which recorded its first measles case in 15 years in an unvaccinated child, Kentucky experiencing its first outbreak of 2025, and Bexar County, Texas, confirming its first case amid the ongoing outbreak. Mexico is also facing a measles outbreak with over 2,900 cases diagnosed, prompting health authorities to expand vaccination campaigns to include people aged 1 to 49 years and to vaccinate migrant workers along the northern border. Baja California has reported 40 suspected cases, and health officials continue efforts to contain the spread. The increase in measles cases highlights ongoing challenges in vaccination coverage and disease control in the region.
