Health Officials Investigate Measles Exposure at Wilmington Children’s Hospital

Delaware health officials announced Thursday they are investigating a potential measles exposure that took place at the emergency department of Nemours Children’s Hospital in Wilmington earlier this week.

The Delaware Division of Public Health confirmed the exposure occurred on February 18, 2026, prompting immediate action from state health authorities.

Health department officials are currently conducting contact tracing efforts to identify individuals who may have been exposed to the highly contagious disease during their visit to the hospital’s emergency room.

As part of their investigation, DPH officials will be reaching out directly to people who were identified as potentially exposed to verify their vaccination status against measles.

The health department’s swift response underscores the serious nature of measles exposure, particularly in a pediatric healthcare setting where vulnerable populations may be present.
