"The Centers for Disease Control and Prevention has confirmed 62 cases of the rare polio-like neurological condition acute flaccid myelitis, also known as AFM, so far this year in the U.S. More than 90 percent of the cases involved children 18 or younger, with an average age of just 4 years old. Cases have been confirmed in 22 states. Officials said they are looking at an additional 65 possible cases of AFM. AFM is an illness that affects the nervous system, specifically the area of spinal cord called gray matter. It causes the muscles and reflexes in the body to become weak or even paralyzed. Cases of AFM are characterized by a sudden onset of arm or leg weakness and loss of muscle tone and reflexes".
