Public‑health officials told the Fargo Cass Public Health Board of Health on July 12 that Cass County’s local measles activity has ended after passing two incubation periods, while the state continues to investigate other cases.
Brett Nissmeyer, epidemiologist with the state of North Dakota, told the board that North Dakota has recorded 35 measles cases year‑to‑date: 17 in Williams County, 10 in Grand Forks County, 7 in Cass County and 1 in Burke County. He said Cass County had passed the 42‑day (two incubation periods) threshold on July 4, indicating the local instance there was over.
Nissmeyer told the board that a new case reported in Williams County appeared to be travel‑related and “not associated with the current … what currently was going on in North Dakota,” based on the state’s investigation.
Fargo Cass Public Health staff described local response measures. Jen (department staff) and Brett said the department hosted two MMR vaccination clinics during the active period in Cass County and administered 46 MMR doses at those clinics; additional walk‑in immunizations continued through regular clinic hours. The department coordinated with Essentia, Clay County Family Healthcare and Sanford to arrange testing locations because public‑health units were not permitted to perform measles testing on site.
Board members asked about situation across the river in Minnesota. Nissmeyer said Minnesota had reported five cases year‑to‑date and that several were near the end of their incubation periods; he noted cases in the Twin Cities and a small cluster linked to a public event.
Why this matters: measles is highly contagious; local vaccination and testing coordination reduce transmission risk and support targeted response.
Discussion and follow‑up: board members asked questions about regional status and thanked staff; no emergency measures or new board actions were taken at the meeting.
