North Dakota has reported eleven measles cases in Williams County and Cass County so far in 2025, with several of the latest cases involving unvaccinated individuals and no known link to prior infections—raising concerns of community transmission. These are the first measles cases reported in North Dakota since 2011.
Measles is a highly contagious viral illness that spreads through respiratory droplets when an infected person breathes, coughs, or sneezes. The virus can linger in the air or on surfaces for up to two hours after the infected person leaves an area, making health care settings particularly vulnerable. Symptoms typically appear 7–14 days after exposure and include high fever, cough, runny nose, red eyes, Koplik spots (small, white or bluish-white spots with a red base that appear inside the mouth, usually on the inner cheeks), and a rash that spreads from the face downward. The MMR (measles, mumps, and rubella) vaccine is safe and highly effective—two doses offer about 97% protection.
The National Picture
As of May 1, 2025:
- 935 cases were reported across 30 U.S. jurisdictions.
- 12 outbreaks were reported, with 93% of cases linked to known outbreaks.
- 96% of those infected were unvaccinated or had unknown vaccination status.
- 121 hospitalizations and 3 deaths were reported.
Health Centers Can Help
Community health centers play a vital role in stopping the spread of measles. Here’s how you can support prevention:
- Educate patients and families about vaccine safety and effectiveness.
- Verify and update immunization records during visits.
- Encourage staff and community vaccinations, especially ahead of travel.
- Prepare front desk and clinical staff to recognize symptoms and follow infection control protocols.
