Health officials investigating link between enterovirus D68, polio-like symptoms

Health officials in British Columbia and Alberta are investigating whether enterovirus D68, which causes respiratory illness, is linked to polio-like symptoms in six young patients.

In B.C., a boy and a male teenager with EV-D68 developed paralytic symptoms that have not improved since they sought hospital care, according to the BC Centre for Disease Control. The two patients are not linked in any way, but both are reporting muscle weakness in one arm.

And health authorities in Alberta said Wednesday that doctors are investigating whether four children with both respiratory and paralytic symptoms are infected with EV-D68.
