The Centers for Disease Control and Prevention says cases of Acute Flaccid Myelitis (AFM) continues to climb across the country.
According to data as of December 7, nine cases were confirmed in Minnesota; compared to one case in North Dakota, nine cases in Wisconsin and two cases in Iowa.
South Dakota is one of 12 states with no confirmed cases of AFM.
AFM is a rare but serious condition. It affects the nervous system, specifically the area of the spinal cord called gray matter, which causes the muscles and reflexes in the body to become weak.
