Delaware Expands Measles Warnings After Hospital Exposure

WILMINGTON, Del. - February 21st, 2026 - Health officials in Delaware are expanding warnings following a confirmed potential measles exposure at Nemours Children's Hospital in Wilmington, raising concerns about declining immunity levels across the state and nationally. The initial alert, issued last year concerning visits to the hospital's emergency department between February 14th and 17th, 2024, has prompted a broader review of vaccination records and a renewed public health campaign aimed at bolstering protection against the highly contagious disease.

Two years on from the initial exposure event, the Delaware Division of Public Health (DPH) continues to monitor the situation closely. While the immediate response in 2024 successfully contained the localized outbreak - tracing and vaccinating potentially exposed individuals - recent data suggests a worrying trend of decreasing measles, mumps, and rubella (MMR) vaccination rates. This decline, experts say, is creating pockets of susceptibility and increasing the risk of larger, more difficult-to-control outbreaks.

"The Nemours exposure served as a critical wake-up call," explains Dr. Anya Sharma, a leading epidemiologist with the DPH. "It highlighted not only the speed with which measles can spread, but also the potential strain it can place on healthcare facilities, particularly pediatric emergency rooms. The fact that we're still seeing residual concerns two years later underscores the long-term implications of even a single exposure in an under-vaccinated community."

The DPH continues to urge anyone who visited the Nemours Children's Hospital emergency department during the specified dates in 2024 to remain vigilant for measles symptoms: fever, cough, runny nose, and a characteristic rash. However, the current focus extends beyond those directly exposed. Public health officials are now actively advocating for comprehensive MMR vaccination for all eligible individuals, emphasizing the importance of maintaining high herd immunity levels to protect vulnerable populations.

Measles is significantly more contagious than COVID-19, spreading through respiratory droplets produced when an infected person coughs or sneezes. A single infected individual can easily transmit the virus to up to nine out of ten susceptible close contacts. This high transmissibility, coupled with the long incubation period (7-14 days before symptoms appear), makes containment challenging. Furthermore, measles can lead to serious complications, including pneumonia, encephalitis (brain swelling), and even death, particularly in infants, young children, and individuals with compromised immune systems.

The reasons behind the declining MMR vaccination rates are multifaceted. A rise in vaccine hesitancy, fueled by misinformation online and a general distrust in medical institutions, is a significant contributing factor. Access to healthcare, particularly in rural and underserved communities, also plays a role. Economic barriers and logistical challenges can make it difficult for some families to obtain timely vaccinations. Furthermore, some parents may be unaware of the ongoing risk of measles, assuming the disease has been eradicated thanks to widespread vaccination efforts in the past.

"We're actively combating misinformation with factual, evidence-based information," says Dr. Rattay, the DPH Director. "We're partnering with community leaders, schools, and healthcare providers to address concerns and emphasize the safety and efficacy of the MMR vaccine. We are also working to improve access to vaccination services through mobile clinics and outreach programs."

The Delaware DPH is not alone in its concerns. The Centers for Disease Control and Prevention (CDC) has reported a nationwide increase in measles cases in recent years, signaling a resurgence of the disease after it was declared eliminated in the United States in 2000. Several states have already experienced outbreaks, prompting calls for increased federal funding for vaccination programs and enhanced surveillance efforts. The CDC website ([ https://www.cdc.gov/measles/index.html ]) provides comprehensive information on measles, including symptoms, prevention, and current outbreak information.

The ongoing situation underscores the importance of proactive public health measures and the collective responsibility to protect community health. The DPH urges all Delaware residents to check their vaccination records and ensure they and their families are fully protected against measles.
