The Centers for Disease Control and Prevention reported Friday that 4,080 confirmed measles cases had been recorded in the United States this year as of Thursday. According to CBS News, the total has far surpassed the 2025 count of 2,289 cases, which was the most in three decades. Most of the cases are among people 19 and younger, and about 95 percent were among unvaccinated people or people whose vaccination status was unknown, the agency said. The CDC says two people have died, a figure it says is subject to change, while Pennsylvania health officials have confirmed five measles-related deaths. According to The Hill, Pennsylvania accounts for over 25 percent of the national total, and cases have been reported in 47 states and Washington, D.C.
