Rare, polio-like illness detected in Pittsburgh area

Add the Keystone State to the list of places now dealing with a mysterious polio-like illness that can partially paralyze children.

At least three cases of acute flaccid myelitis (AFM) have been detected in the Pittsburgh area. Doctors say the sickness impacts the spinal cord and carries symptoms similar to polio. While rare officials over the U.S. are dealing with a spike in cases.

The discoveries in Western Pa. come days after health officials in Minnesota announced at least six confirmed cases of a disease that can lead to paralysis.

So far, experts say they can neither pinpoint the cause or a treatment for the recent cases.
