Cases in the ongoing measles outbreak have risen to 258 across Texas, New Mexico and Oklahoma, and state health departments are urging more people to get the measles-mumps-rubella vaccine.

By Chad Terhune (Reuters) -As a measles outbreak spreads across West Texas, Dr. Ana Montanez is fighting an uphill battle to convince some parents that vitamin A - touted by vaccine critics as effective against the highly contagious virus - will not protect their children.

In Texas specifically, a total of 223 people have contracted measles since the outbreak began in January, with at least 29 people, mostly children, requiring hospitalization. One child, who was unvaccinated, has died from measles, while a second unvaccinated person’s death is currently being investigated by health officials.

Less than three full months into 2025, US measles cases have outpaced last year’s total, as a worrying outbreak linked to two deaths continues to spread.

Measles cases have surpassed last year’s total less than three months into the year, as the outbreak in West Texas continues to spread.

The number of measles cases associated with an outbreak in western Texas has grown to 259, according to new data released Friday.

Los Angeles County in California, Suffolk County in New York and Howard County in Maryland detected their first confirmed cases of measles this year, while Oklahoma reported two possible cases, local health authorities said this week.
