The North Dakota Department of Health and Human Services (HHS) is reporting one confirmed case of measles in Williams County. This is the first measles case reported in North Dakota in 2026.
The individual was unvaccinated and acquired measles out-of-state.
HHS has identified and notified individuals who may have been exposed. There are no community exposure locations requiring public notification.
In 2025, North Dakota had 36 confirmed measles cases. Those were the first cases confirmed in the state since 2011.
“This case serves as a reminder to North Dakotans that measles continues to circulate worldwide and in the United States,” said Molly Howell, director of the HHS Disease Control and Forensic Pathology Section. “The measles, mumps and rubella (MMR) vaccine is 97% effective after two doses. People who are vaccinated and exposed to measles are unlikely to develop the disease. MMR vaccination is critical to preventing the spread of measles in the community, and anyone who is eligible and not yet vaccinated is encouraged to contact a trusted health care provider.”
Because the majority of North Dakotans are vaccinated, the risk to the general public is low.
The MMR vaccine is recommended starting at 12-15 months of age, with a second dose at 4-6 years of age. Children who have already received two doses of MMR are considered fully vaccinated.
Adults born before 1957 are generally presumed immune due to natural immunity. Adults born in 1957 or later should ensure they have received at least one documented dose of MMR.
Individuals unsure of their vaccination status are encouraged to consult their health care provider. Immunization records can be reviewed at hhs.nd.gov/IRR or by contacting a provider.
Measles is a highly contagious viral illness that can be serious, particularly for young children and individuals with compromised immune systems. Symptoms often include fever, cough, runny nose and eye irritation, followed by a widespread rash.
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.
People who think they may have measles should contact a health care provider prior to seeking testing or care to prevent spread to others in the health care facility. There is no specific medical treatment for measles, though antibiotics may be used when people with measles develop a secondary bacterial infection.
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.
