A new suspected case of the mysterious paralyzing illness believed to be acute flaccid myelitis (AFM) is being investigated in Washington.
The boy, who is younger than six, was hospitalized after his arm suddenly became paralyzed. He had previously been dealing with a fever and respiratory issues. His health is reportedly improving after treatment.
The CDC is now analyzing the case to see if it was in fact AFM. This is one of 11 cases being investigated in Washington of the mysterious disease.
Experts say there is no single known cause of AFM. Researchers have linked some viruses and germs to AFM, including common germs that can cause colds and sore throats and respiratory infections. AFM can also be caused by poliovirus and non-polio enteroviruses, mosquito-borne viruses, and possibly via non-infectious conditions.
