While states near Texas like New Mexico, Oklahoma, and Kansas have some of the higher case counts, the majority of U.S. states have so far seen only 1–9 measles cases this year so far.
Measles cases have been confirmed across 39 different states as of July 15th, 2025.
MMR Vaccination Rates Falling Short for Herd Immunity
A key contributor to this surge in cases is that MMR vaccine coverage among kindergarteners dropped to 92.7% in 2023–24, below the 95% threshold required for herd immunity. This dip in vaccination makes communities more vulnerable to outbreaks, with public health officials raising alarms about the need to reverse this trend.
There have been three deaths from measles in the U.S. this year so far, two children in Texas and an adult in New Mexico.
