Measles Resurgence Triggers Severe Brain Swelling and Sepsis Cases Across the U.S.
Recent data from Utah and South Carolina reveal alarming rates of encephalitis and sepsis in unvaccinated measles patients. Read the latest health findings.
Critical Complications Emerge in Measles Outbreaks
As vaccination rates continue to falter across the United States, the medical community is grappling with a resurgence of measles that is landing more patients in the hospital with severe, life-threatening complications. New reports focusing on significant outbreaks in South Carolina and Utah have identified that beyond the standard respiratory distress, patients are increasingly suffering from dangerous conditions including brain swelling—known as measles encephalitis—and sepsis.
Dr. Katherine Richardson and her team at Prisma Health Greenville Memorial Hospital, documenting their findings in the New England Journal of Medicine, highlighted a grim reality: two out of 13 hospitalized patients in South Carolina developed encephalitis. This grave complication necessitated extended medical care and, in one instance, a transfer to an inpatient rehabilitation facility. These findings underscore the volatility of a disease once considered eradicated.
Clinical Data Reveals Widespread Vulnerability
Data from Utah paints a similarly concerning picture. According to Dr. Anna Jones of the Utah Department of Health and Human Services, writing in NEJM Evidence, the hospitalized cohort showed systemic physiological distress. Among those with laboratory results available, 54% exhibited hyponatremia or lymphopenia, while 37% suffered from thrombocytopenia. The strain on these patients was immense, with over half requiring supplemental oxygen and 78% needing intravenous fluid support to manage their condition.
Across both states, hypoxemia and pneumonia remain the primary drivers for hospital admission. However, the presence of sepsis, electrolyte imbalances, and shock indicates that measles is far from a benign childhood illness. The South Carolina report also noted a high prevalence of secondary infections, including sinusitis and otitis media, complicating the recovery process for many of the 81 patients identified in that region.
The Unvaccinated Population at Highest Risk
Public health experts point directly to the decline in immunization coverage as the catalyst for these outbreaks. Dr. Paul Offit, director of the Vaccine Education Center at the Children's Hospital of Philadelphia, maintains that the current situation is entirely preventable. He emphasizes that the resurgence is fueled by a critical segment of the population choosing to forgo vaccinations, leaving both children and adults vulnerable to preventable severe morbidity.
As of July 9, 2026, the CDC confirmed 2,238 measles cases across 32 distinct outbreaks. This trajectory suggests the U.S. will soon surpass the 2,289 cases recorded in 2025. The demographic data is stark: 93% of patients in 2025 and 2026 were either unvaccinated or possessed an unknown vaccination status. In Utah, 85% of the 602 measles cases involved unvaccinated individuals, with children under 18 representing the majority of hospitalizations.

Frequently Asked Questions
What are the most severe complications identified in the recent measles outbreaks?
Medical researchers identified life-threatening issues such as measles encephalitis (brain swelling), sepsis, and shock. These conditions often require prolonged hospital stays and specialized rehabilitation.
Why are measles cases rising in the United States?
The primary driver is a decline in vaccination rates, as a significant portion of the population chooses not to vaccinate. This lack of immunity has allowed the highly contagious virus to spread rapidly through communities.
Who is most at risk for hospitalization due to measles?
Unvaccinated individuals, particularly those 18 years of age and younger, represent the vast majority of hospitalizations. Reports indicate that over 90% of those admitted to hospitals during recent outbreaks were unvaccinated.
