people from the Minot area.
All of the cases involved current or former residents

North Dakota Department of Health. Since then, the federal Centers for
Disease Control and Prevention has linked four additional cases to the
first three. Samples from 28 more people have been sent to the CDC to be
tested, and there is the possibility that more people might be referred
