Measles math: What to know about 1,001 measles cases across the country

The U.S. has seen 1,001 confirmed measles cases this year, setting a high mark surpassing previous years since 2019. Outbreaks have surged across multiple states, with west Texas reporting the largest cluster at over 700 cases recently. Despite vaccination efforts and two deaths reported in Texas and New Mexico, herd immunity remains elusive as some areas, like Gaines County, Texas, fall short of the required 95% vaccination rate—nearing 82%. The U.S., which achieved measles elimination 25 years ago, faces a renewed risk of losing this status if major outbreaks persist within the next year.
