Medical Examiner Finds NJ Preschooler Died Due to Enterovirus 68

Virus is suspected of sickening children in at least 43 states.

Brain and lymph node swelling in the child was then determined to be a result of the virus.

At least four other patients who tested positive for the enterovirus 68 have died, and CDC and local medical officials are investigating whether the virus played a role in their deaths.

The New Jersey child from Hamilton Township in Mercer County is the state's first death involving enterovirus 68, according to the New Jersey Department of Health.

"Our thoughts remain with the family at this very difficult time," Health Commissioner Mary O'Dowd said. "While the child has tested positive for EV-D68, the cause of death has not yet been determined and it is unclear if [enterovirus 68] played a direct role or was a contributing factor in his death."

In Colorado, CDC and local health officials are investigating whether limb weakness and paralysis reported in nine children was associated with the enterovirus 68.
