A measles outbreak originating in Texas has expanded into neighboring regions, raising alarms among global health authorities. The U.S. Centers for Disease Control and Prevention (CDC) reports 308 cases across 15 states as of early 2025 — surpassing 2024’s total — with infections now confirmed in Mexico. Health officials in Chihuahua, a Mexican state bordering Texas, identified 22 cases linked to cross-border transmission.
The resurgence highlights challenges posed by declining vaccination rates in parts of the southern U.S., where exemptions have risen in recent years. Public health experts warn that densely populated urban centers and travel hubs could accelerate spread. While no fatalities have been reported, hospitals in affected areas are preparing isolation units amid fears of strained healthcare systems.
Global health organizations emphasize measles’ highly contagious nature, urging travelers to verify immunization status. The outbreak coincides with increased regional mobility ahead of summer holidays, prompting advisories for families and business travelers visiting Texas and northern Mexico.
