Grand Forks, North Dakota – Measles cases in North Dakota have climbed to 11 confirmed infections, with health officials confirming that two individuals required hospitalization. The North Dakota Department of Health and Human Services reported that additional cases in Pembina County have significantly increased exposure concerns across eastern parts of the state.
Health authorities are urging residents, particularly those who are unvaccinated, to review exposure locations and take precautionary steps to prevent further spread of the highly contagious virus.
Incident Overview
According to state health officials, Pembina County recorded four new confirmed measles cases this week, bringing the county’s total to nine. In neighboring Walsh County, one additional case was confirmed involving a person who had traveled to Pembina County.
The state has identified 26 potential exposure sites across eastern North Dakota between January 30 and February 11, increasing concerns about community transmission.
Timeline of Reported Cases
The first confirmed measles case in North Dakota for 2026 was reported earlier this year in Williams County. That case was believed to be linked to out-of-state travel. Since then, cases have expanded to multiple counties, primarily in eastern North Dakota.
Of the 11 total confirmed cases, nine individuals were either unvaccinated or had unknown vaccination status, highlighting concerns among public health experts about immunization gaps.
North Dakota also experienced a previous outbreak in 2025, reporting 36 measles cases across Williams, Grand Forks, Cass, and Burke counties.
Details from Health Officials
Dr. Marc Nielsen, medical director of primary care at Altru Health System in Grand Forks, described the situation as alarming given the contagious nature of the virus.
“Nine out of 10 potential contacts can come down with the illness. It’s that contagious. It puts a lot of people at risk.”
Nielsen emphasized that measles spreads rapidly, especially in communities with lower vaccination rates.
Ashley Krone, disease prevention team leader for Grand Forks Public Health, urged residents to carefully review the exposure site list released by the state.
“Even if we don’t have a case in the county at this time, these exposure locations are just a reminder that measles are just a car ride away and can arrive at any time.”
Health officials recommend that unvaccinated individuals who may have been exposed remain at home for 21 days to help prevent further spread.

Measles Symptoms and Transmission Risks
Measles typically begins with fever, cough, runny nose, and red or irritated eyes, followed by a distinct red, blotchy rash. One of the most concerning aspects of the virus is that individuals can transmit it up to four days before the rash appears, making early containment difficult.
Dr. Nielsen noted that the measles vaccine is highly effective, providing 93% protection after one dose and 97% after two doses.
Health experts stress that vaccination remains the most effective tool to prevent outbreaks and protect vulnerable populations, including young children and immunocompromised individuals.
National Context
The rise in cases in North Dakota comes amid a broader national increase. The Centers for Disease Control and Prevention (CDC) reported 72 additional measles cases this week, bringing the nationwide total to 982 cases across 26 states in 2026. In comparison, 2025 saw 2,281 cases across 44 states.
Public health officials say these increases underscore the importance of maintaining strong vaccination coverage to prevent large-scale outbreaks.
Public Health Guidance
Health authorities advise:
- Unvaccinated individuals should avoid large gatherings in affected counties
- Anyone who believes they may have contracted measles should call ahead before visiting a clinic
- Vaccinated individuals do not need to change their daily activities
- Residents should monitor symptoms and seek medical advice if exposed
Officials also remind residents that measles can spread quickly in schools, childcare centers, healthcare facilities, and community events.
Conclusion
The increase to 11 measles cases in North Dakota, along with multiple exposure sites and hospitalizations, has prompted renewed concern among health officials. With most cases involving unvaccinated individuals, experts are emphasizing prevention through vaccination and community awareness.
