Measles cases in the U.S. are at their highest in more than three decades. The U.S. Centers for Disease Control and Prevention says the U.S. has 1,288 cases since the beginning of the year.

According to the Centers for Disease Control and Prevention, 1,267 cases of measles had been confirmed in the U.S. as of July 1, 2025, including cases in Palmetto State neighbors Georgia and North Carolina along with 35 other states. The CDC has confirmed three measles deaths so far this year.

While measles symptoms typically resolve in a few weeks, the virus can cause pneumonia, making it difficult for patients, especially children, to get oxygen into their lungs. It may also lead to brain swelling, which can cause lasting damage, including blindness, deafness and intellectual disabilities.

This year is the worst for measles spread in the U.S. since 1991. The news comes as Missouri has become the 18th state with an outbreak in 2025.

Measles cases in the US have reached their highest level since 1992, driven largely by an ongoing outbreak in west Texas.

The state will provide updates online on Tuesdays and Fridays. The deaths of two children have been linked to the measles outbreak in West Texas.

The University of Texas and Austin Public Health created a measles simulator for school districts and private schools around the county to better understand their risks.
