The North Dakota Department of Health and Human Services (HHS) is reporting one confirmed case of measles in Dunn County. This is the first measles case reported in Dunn County. The individual acquired measles out of state.
North Dakota has a total of 36 confirmed cases of measles in seven counties to date in 2026, and five individuals have been hospitalized. The United States has confirmed 1,792 cases in 2026.
As measles cases continue to occur in the U.S., Canada and other countries, individuals are encouraged to closely monitor for any signs or symptoms of measles and to contact a healthcare provider for guidance and testing if symptoms develop.
Symptoms often include fever, cough, runny nose and eye irritation, followed by a widespread rash.
Who is at risk?
Measles is a highly contagious viral illness that can be serious, particularly for young children and individuals with compromised immune systems. Individuals who are unvaccinated are most at risk. These individuals are encouraged to talk to a trusted healthcare provider about vaccination.
Measles spreads easily through the air and can remain in a room and on surfaces for up to two hours after a person who is contagious leaves that space. Individuals with measles are contagious for several days before and after symptoms appear.
Those who think they have measles should call first before seeking healthcare to avoid exposing others to measles. Individuals who are not vaccinated and are exposed to measles should stay home and avoid public settings for 21 days after exposure. Unvaccinated individuals who are exposed to measles should talk to their healthcare provider about options to reduce the risk of illness or severe outcomes.
Measles vaccine recommendations
The MMR vaccine remains the most effective way to prevent measles. One dose of MMR vaccine is about 93% effective at preventing measles; two doses are about 97% effective.
MMR is recommended starting at 12-15 months of age with a second dose at 4-6 years of age. Individuals who have already received two doses of MMR are considered fully vaccinated.
Adults born before 1957 are generally presumed immune due to having a history of measles illness. Adults born in 1957 or later should ensure they have received at least one documented dose of MMR.
MMR vaccines are available through most clinics. For families in need, the federally funded Vaccines for Children (VFC) Program provides vaccines at no cost through participating providers.
Individuals unsure of their vaccination status are encouraged to consult their healthcare provider. North Dakota Immunization records can also be reviewed at hhs.nd.gov/IRR.
