Map of Measles Cases Spiking as Trump Admin Overhauls Vaccine Advice
U.S. measles cases hit 2,566 as outbreaks surge nationwide, with 94% linked to ongoing transmission.
The U.S. is currently experiencing its highest measles caseload in over three decades, with the Trump administration pushing a sweeping overhaul of childhood vaccine recommendations. As of August 13, the CDC reported 2,566 confirmed measles cases nationwide, with Wisconsin among the 47 states reporting infections. The administration's new "Gold Standard Childhood Vaccine Recommendations" would restructure how and when children receive vaccines, causing concern among pediatric experts and health officials.
Wisconsin's MMR coverage for 24-month-olds has dropped from 84.9% in 2019 to 79.8% in 2025, leaving thousands more children vulnerable to infection. The geographic spread of cases mirrors declining MMR vaccination rates in many states, particularly in regions with growing vaccine hesitancy and increased school-entry exemptions.
