BISMARCK -- A Burleigh County resident initially thought to have measles has now tested negative for the disease, the North Dakota Department of Health said in a news release Thursday afternoon, Sept. 6.

The Centers for Disease Control and Prevention ran a subsequent test on the sample, per protocol.

“Measles is one of the most contagious diseases in the world,” said Molly Howell, immunization program manager for the NDDoH. “We acted quickly and appropriately based on the testing and information that we had on hand at the time to prevent the spread of measles in the community. We appreciate the cooperation of this individual, schools and community members in response to this situation.”

The public was notified on Wednesday about a reported measles case, which would have been North Dakota’s first case in seven years. Any children or employees who were excluded from school or other activities may return, the news release said.

Laboratory tests can sometimes produce false positives, though that’s rare, the state health department said.
