Polio was eradicated from the U.S. months ago, but now reports of a polio-like illness is on the rise. The US Centers for Disease and Prevention says Acute flaccid myelitis is a rare illness that anyone can get. As of August 2016, 50 people in 24 states were confirmed to have AFM. Most of the cases were children.
AFM affects a person’s nervous system, specifically the spinal cord, causing paralysis. The CDC says they are testing and researching the disease, but at this point they don't know the cause or how to prevent it. They say practice typical illness prevention -- wash your hands and protect yourself against mosquito bites.
