  • Mystery Polio-Like Illness Linked to New Virus

    For a while, researchers studying a mysterious polio-like illness in Colorado last year felt like they were coming close to pinpointing the cause of the disease. Now they're not so sure.

    According to a report in livescience, new research has uncovered that while there may be a connection between enterovirus D68 (EV-D68) and cases of acute flaccid paralysis suffered by children in various parts of the United States, new studies have found the presence of another virus in at least 1 patient. That virus, called enterovirus C105, belongs to the same species as the polio virus.

    The patient—a 6-year-old girl—tested negative for EV-D68. Hers was the first report of enterovirus C105 in the US.

    The discovery further clouds speculation that the EV-D68 virus was at the root of the neurological impairments.

    "Although cases of flaccid paralysis associated with isolation of EV-D68 from spinal fluid have been reported, the role of EV-D68 in the current outbreak remains to be determined," authors write in a report to the US Centers for Disease Control and Prevention. "As the results from this case indicate, it is possible that other viral pathogens with neurovirulence may be contributing to the outbreak."
