Of the 1,288 measles cases nationwide, a majority of them come from Texas. The Lone Star state's 753 confirmed cases are the most among the other 30-plus states with cases, according to CDC data. New Mexico's 95 cases are the second-highest in the nation, followed by Kansas' 87 cases.

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.

The Texas Department of State Health Services has reported no new measles cases linked to the West Texas outbreak this week.

Texas health officials on Tuesday said the county at the center of the state's measles outbreak is no longer classified as an outbreak county.

Measles became a nationally notifiable disease in 1912, which meant all health care providers and labs were required to report all diagnosed cases, according to the CDC.

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.
