WASHINGTON (CNN) — A rare polio-like disease that causes paralysis is affecting children across the country.

The Centers for Disease Control and Prevention said on Tuesday, October 16th, 2018, that 127 cases are under investigation.

The medical name is acute flaccid myelitis or AFM, and it’s a growing health concern. 

The 62 confirmed cases occurred in 22 states. More than 90-percent are in patients 18 or younger with an average age of 4 years old. 

The CDC said AFM could have several possible causes. That could be environmental, genetic, or viral. And despite its similarities to polio, there is currently no vaccine.

It’s important to note the illness is rare, but prevention techniques are still encouraged.

Just like you would for the flu or common cold, cover your mouth when you cough, sneeze into your elbow, and wash your hands frequently.
