Acute Flaccid Myelitis

Acute Flaccid Myelitis is a syndrome characterized by sudden onset of limb weakness, sometimes accompanied by facial drooping or difficulty speaking. A number of infectious germs have been demonstrated to cause AFM, including poliovirus and other non-polio enteroviruses, flaviviruses (such as West Nile Virus), and adenoviruses. A condition where the body’s immune system attacks and destroys body tissue that it mistakes for foreign material may also cause AFM.
