A newly discovered strain of a polio-like virus may be responsible for at least some of the mysterious cases of paralysis in U.S. children over the last year, a new study suggests.
More than 100 children in 34 states have developed muscle weakness or paralysis in their arms or legs, according to the Centers for Disease Control and Prevention. Previously, researchers linked a virus called enterovirus D68 (EV-D68) with some of these cases.
But the new study suggests another strain of enterovirus — called enterovirus C105, which is in the same family as the polio virus — is more likely to blame for the cases, Live Science
The study should make researchers aware that "there's another virus out there that has this association" with paralysis, said study co-author Ronald Turner, M.D., a professor of pediatrics at the University of Virginia School of Medicine. "We probably shouldn't be quite so fast to jump to enterovirus D68 as the [only] cause of these cases."
The findings are based on the case of a 6-year-old girl who was diagnosed with the condition and tested positive for enterovirus C105 infection, but negative for EV-D68.
This virus was only recently discovered, and the new study is the first report of enterovirus C105 in the United States, the researchers said.
