Colorado health officials are reporting that several children, including some that tested positive for the Enterovirus D68 (EV-68) have also reported neurological symptoms not commonly associated with the virus, including muscle weakness and paralysis. Nine children were identified between August 8 and September 17; all children are from the Denver area and are being treated at Children’s Hospital Colorado in Aurora, CO. Reported symptoms include fever and breathing problems two weeks before developing limb weakness but symptoms are not believed to be related to polio because most of the children are up-to-date on their polio vaccinations. Four of the eight children tested by the CDC tested positive for EV-D68 and two others tested positive for other unidentified strains of an enterovirus. The CDC is advising clinicians to be alert for any acute onset of limb weakness and to report patients who develop limb weakness and who have had a magnetic resonance imaging (MRI) test that shows lesions in the gray matter of the spinal cord.
