The U.S. has reported over 2,000 measles cases in just five months, with the CDC confirming 57 new infections on Friday, according to CIDRAP. South Carolina and Utah have seen significant outbreaks, while Florida’s situation remains underreported, per NBC News.
Rapid Spread in Key States
The Centers for Disease Control and Prevention (CDC) reported 2,030 confirmed measles cases as of June 5, 2026, surpassing the 2,288 total from all of 2025, which marked the highest annual tally since 1991. South Carolina led with 669 cases, though its outbreak has since waned, while Utah reported 486 infections, with only nine new cases in the past three weeks, suggesting a slowdown CIDRAP. Florida, meanwhile, recorded 154 cases through May 30, according to state health data, though the Florida Department of Health has avoided formal briefings on the outbreak NBC News.

Over 92% of patients remain unvaccinated or have unknown vaccination status, with 21% of cases involving children under five and 72% affecting those up to 19 years old. Hospitalization rates dropped to 6% this year, down from 11% in 2025, though no deaths have been reported CIDRAP. The South Carolina Department of Public Health confirmed a recent case involving an unvaccinated adult who traveled internationally, noting the exposure source remains unknown CIDRAP.
Public Health Response Innovations
In Virginia, the Piedmont Health District partnered with Centra Health to deploy a mobile response program, allowing healthcare workers to conduct home visits for suspected cases. Dr. Chris Thomson, executive vice president for Centra Health, explained the initiative aims to prevent hospitalizations by providing early interventions like IV fluids for dehydration and identifying household contacts NBC News. “By being able to get to someone who calls at an early stage of their illness… we’re able to identify whether or not there are others who are ill,” Thomson said, highlighting the program’s dual role in treatment and surveillance NBC News.
This approach contrasts with traditional methods, where patients often sought care in emergency departments, potentially spreading the virus. While vaccines are available, the initiative prioritizes isolation and quarantine guidance in communities with low vaccination rates, as noted by Piedmont Health District Director Dr. Maria Almond NBC News.
Contrasting Regional Trends
Utah’s outbreak, which peaked with 675 cases since last summer, has shown signs of decline, though it remains a major hotspot. Florida’s cases, concentrated in Collier County around Ave Maria University, have stabilized with no new infections reported in over a week. In contrast, Pennsylvania and Virginia have seen emerging clusters, with 60 and 91 cases respectively, mostly in Lancaster, Lebanon, and central Virginia NBC News.
The CDC’s data reveals a shift in outbreak patterns: while 48 outbreaks were recorded in 2025, only 30 have occurred this year.
