Researchers at the U of M say a virus is behind a series of polio-like illnesses that affected several Minnesota kids last fall. A new report shows enterovirus-D68 was found in the spinal fluid of one of the six children who suffered the effects of Acute Flassic Myelitis (AFM).

Lead author of the report, Dr. Heidi Moline, says the virus is…” predominantly a mild illness, but in some children and we don’t know why, they develop a more severe illness and it has neurological affects and that’s what we really have to continue to investigate and learn more about this virus.”

AFM can cause sudden onset limb weakness, especially in children. One girl from last fall’s outbreak remains hospitalized.
