The CDC has updated the U.S.’s measles case total in 2025 to 1,912, adding 84 cases since last week. CIDRAP has the news.
The U.S. is at risk of losing its measles elimination status because of “ongoing transmission chains from a West Texas outbreak that began early last year and sickened roughly 800 people.” 88% of cases in the U.S. this year have been outbreak-associated, and there have been a total of 47 outbreaks recorded thus far. Utah, Arizona, and South Carolina are currently seeing large outbreaks.
In South Carolina, “281 students at eight states in the Upstate region are in quarantine. That state has 114 cases, 111 associated with the Upstate outbreak.” The highest activity in Utah is in a “southwestern region of the state that borders Arizona.” That outbreak now has 254 cases, and is the “second largest U.S. outbreak this year after West Texas.” Arizona officials confirmed 21 new measles cases in the past week.
92% of patients with confirmed measles cases are “unvaccinated or have unknown vaccination status. Three percent have had one dose of measles-containing vaccine, and 4% have had two doses.”
