United States: The Centers for Disease Control and Prevention (CDC) documented 800 measles diagnoses throughout 25 U.S. jurisdictions during Thursday of 2025. The recent figure surpasses 712 cases counted on April 10 by a significant margin. Texas and New Mexico comprise among the states where measles outbreaks occurred.
Outbreaks Responsible for Most Infections
The CDC noted that just ten outbreaks accounted for 94% of all confirmed cases this year—up significantly from 2024, when outbreaks caused 64% of total cases. The data highlights how localized transmission events are fueling a national rise, as reported by Reuters.
Texas Leads With Nearly 600 Cases
Texas alone has documented 597 measles cases—an increase of 36 since the previous week. The state remains the epicenter of the 2025 measles surge.

Children under five years old have been particularly affected, accounting for 249 of the total cases. Of those, 47 required hospitalization. Across all age groups, the overall hospitalization rate stands at 11%.
Vaccination Gaps Remain a Major Issue
Research data from the CDC showed that patients infected with measles were mostly unvaccinated or had missing vaccination records amounting to 96 percent. Experts confirm that the collected information reveals an urgent necessity to enhance vaccine protection along with public health instruction, as reported by Reuters.
Experts Cite Confusion, Lack of Support
According to Reuters reports medical specialists in pediatric care and infectious diseases state that untrusted medical recommendations and unclear therapeutic directions while having insufficient backing from federal health agencies have created challenges for national measles response.
