North Dakota Health and Human Services (HHS) has confirmed a total of seven measles cases in 2026, with six reported in Pembina County and one in Williams County. Two individuals have been hospitalized, and five of the cases involve adults over the age of 19.
According to HHS, people who were contagious with measles visited several public locations across the state during their infectious period. Those who were present at these sites during specific dates and times may have been exposed to the virus. Details about potential exposure locations and guidance for those who may have been affected are available on the HHS website at hhs.nd.gov/measles.
Unvaccinated individuals are considered at highest risk for contracting measles. HHS stated, “Herd immunity is achieved when more than 95% of a community is vaccinated, protecting those who are too young, older, immunocompromised, or otherwise unable to receive vaccination. When vaccination rates drop, everyone’s risk increases.”
The department follows Centers for Disease Control and Prevention (CDC) guidelines by conducting contact tracing for all identified contacts and exposure sites. “Individuals who may have been exposed could be contacted by health officials with guidance regarding quarantine, symptom monitoring and vaccination. Public locations are posted on the HHS website,” according to HHS.
Schools, child care facilities, and other institutions adhere to public health recommendations and state law regarding temporary exclusion of unvaccinated students during outbreaks. Families maintain full authority over medical decisions for their children, including lawful immunization exemptions. HHS noted that “those who choose an exemption sign a state form acknowledging that, in the event of an exposure or outbreak, temporary exclusion from school or activities may be recommended to help protect public health.” This approach aligns with communications alerting families about possible exposures.
For those who may have been exposed to measles, HHS advises monitoring for symptoms such as fever, cough, runny nose, red eyes and rash. Individuals should contact their healthcare provider immediately if symptoms develop and before visiting any healthcare facility to prevent further spread. People with weakened immune systems due to disease or medication should call their provider right away after learning about an exposure rather than waiting for symptoms.
HHS also states that vaccination can still prevent or reduce illness if administered promptly after exposure.
