US measles cases exceed 2,000 in 2026, nearing worst year in decades
8 reported
The United States has recorded more than 2,000 confirmed measles cases so far in 2026, approaching the total of 2,228 cases recorded in all of 2025, according to a report from The Guardian. The outbreak is on track to become the worst year for measles in decades, with the virus continuing to spread in unvaccinated and under-vaccinated communities, including among infants too young to be vaccinated. Experts believe the true number of cases is about three times higher than the 2,030 cases recorded on June 4. Cases in Utah appear to be winding down, while cases in Virginia and Pennsylvania appear to be increasing. The outbreak has been linked to low vaccination rates, limited public health resources, and the loss of federal funding for public health. In South Carolina, the outbreak is officially contained after reaching nearly 1,000 documented cases, with a 162% jump in vaccinations in Spartanburg County in January. A new analysis found a 38.7% increase in exposures to vitamin A reported to US poison control centers in early 2025, alongside surges in internet searches for the unproven treatment.
