Measles Cases Reach 483 Throughout the U.S.

The measles outbreak centered in western Texas has grown to 400 infections. CIDRAP has the news.

U.S. cases are quickly approaching 500, and the nation is on track for its worst year for measles infections since 2019. The Texas Department of State Health Services reported 73 more cases on March 28, and they expect “more cases to be reported in affected and surrounding areas” due to how contagious the virus is.

Of the 400 Texas measles patients, only 2 were “known to have received two recommended measles vaccine doses, and the rest had unknown status or were unvaccinated.” New Mexico also reported another new case, raising its total to 44, as border counties continue to be affected by the western Texas outbreak.

Meanwhile, the New Jersey Department of Health has issued an “alert about potential exposures related to two unrelated confirmed measles cases in people who aren’t residents of the state.”

The national total of measles cases in the U.S. now stands at 483. 93% of those cases are part of outbreaks. Kansas and Ohio have recently added cases to their outbreak totals, and Oklahoma has “reported nine cases…in an outbreak linked to the Texas outbreak.” Of the people infected in the U.S., “97% were unvaccinated or had unknown vaccination status.” Cases this year are tracking “well above the 285 cases reported for all of 2024 and are at the highest level since 2019 when 1,249 cases were reported.”

HPN has previously reported on the uptick in measles cases in the U.S. throughout 2025.
