Ohio health officials have confirmed that the state has had one case this year of acute flaccid myelitis (AFM), a rare, polio-like condition.

The Ohio Department of Health said their lone case was confirmed by the Centers for Disease Control and Prevention.

The condition that mostly strikes children has seen an increase this year, according to the CDC.

The CDC announced Tuesday there have been 62 confirmed cases in 22 states.

CDC officials say they haven't found the cause. Some possible suspects, such as polio and West Nile virus, have been ruled out. Another kind of virus is suspected, but it's been found in only some of the cases.

About 90 percent of the cases are children who have suffered muscle weakness or paralysis, including in the face, neck, back or limbs. The symptoms tend to occur about a week after they had a fever and respiratory illness.

Officials said the jump in cases appears to be following an every-other-year pattern with similar waves of the illness in 2014 and 2016.

The cases in 2014 and 2016 were partly attributed to particular strains of respiratory germs called enteroviruses, which spread the most in the summer and fall.

Most people infected with enteroviruses suffer only minor symptoms like cough and runny nose. And though enteroviruses have been detected in some paralysis cases, it hasn't been found in others, CDC officials say.
