(North Dakota Monitor) – North Dakota health officials warned Thursday about possible community spread of measles after a case was identified in Pembina County.

The state’s second case of the disease for 2026 involves an unvaccinated adult who was required to be hospitalized, according to the Department of Health and Human Services. The person had not traveled and likely was exposed in North Dakota, though officials were still working to determine the source.

The case in far northeastern North Dakota is not connected to the first North Dakota measles case of 2026, reported in Williams County in the northwest part of the state last week. That case also involved an unvaccinated adult, but that infection was linked to out-of-state travel.

For the Pembina County case, health officials are identifying and notifying people who may have been exposed.
