The family's nightmare began when Morgan Maurer caught a cold in October that just wouldn't go away.
Her parents, Athena and Greg Maurer, were told she had everything from a chest infection to pneumonia and rhine neck.
But then the diagnosis came back as Enterovirus, even though Morgan doesn't fall into a high-risk category.
"Her arm wasn't moving at all. Her leg, she couldn't stand, couldn't walk," said her mother. The family moved from Duncan, B.C. to Vancouver for Morgan's treatment at Sunny Hill Health Centre for Children.
Doctors say reactions to Enterovirus D68 like Morgan's are rare. The potentially deadly virus hit North America hard this fall.
As of Nov. 26, there have been 207 EV-D68 cases in the province, according to the B.C. Centre for Disease Control, of which 133 required hospitalization.
Children under 10 made up the the majority of hospitalizations.
Since mid-August, four cases of neurological illness and two deaths associated with EV-D68 infection have been reported in B.C. — although it's unclear to what extent EV-D68 infection was a cause or contributing factor.
As for four-year-old Morgan Maurer, she is now recovering, but she is still unable to walk and it's unclear if she will ever regain full mobility of her arm.
"She's strong, very strong," said her father, Greg.
