In the past calendar month , six children in Minnesota have been diagnosed with a rare , potentially paralyzing and deadly queasy system condition call acute flaccid myelitis ( AFM ) , instigate an investigating by the Minnesota Department of Health ( MDH ) .

presently , little is known about how AMF get and there are no specific treatments . Though aesculapian researchers trust environmental toxin and genetics may come into play as well , the condition appears to come up as a complication of sure viral respiratory infection in tiddler – very few adult example have been reported . Viruses in theenterovirus genus – a radical that includes the common common cold and the infantile paralysis virus – are most closely associated with AFM , though past compositor’s case have also been link to West Nile virus , Japanese encephalitis virus , Saint Louis encephalitis , and adenovirus . grant toa statementreleased by the agency , the State Department commonly sees about one slip of AFM per year , though there was a nationwide capitulum in 2014 accompany an outbreak of an enterovirus called EV-68.CNN reportsthat there were 120 entire cases nationwide in 2014 , but only 21 in 2015 .

The onslaught of AFM is characterize by sudden failing or palsy in one or more limbs , sometimes accompany by neck failing or stiffness , droop eyelids or other facial muscles , trouble swallowing , and/or dim manner of speaking . Per the Centers for Disease Control and Prevention ( CDC ) , the most hard symptom of AFM is respiratory failure triggered by subvert of the diaphragm muscles . If this begins to occur , the patient requires urgent aesculapian interference so they can be localise on a ventilator . In a small number of cases , the physical process driving AFM have triggered other serious neurologic complication , leading to death .

These deterioration are because of wound in thegray matterof the encephalon and spinal cord , a diagnostic sign that may be discover on MRI CAT scan . Most unnatural individuals also show increased resistant cells in their cerebrospinal fluid . No retiring patient have shown changes in knowledge or mental state .

“ What we ’re look at is a disease identical in most respects from traditional infantile paralysis , in terms of its symptom , ” Dr Keith Van Haren , a paediatric brain doctor at Stanford University School of Medicine , toldNeurology Todayin 2014 . “ Until now it was a really rare bird . Before 2012 , we see maybe one lawsuit every five years that was n’t attributable to West Nile . Since 2012 , we ’ve learn many more sheath . And since just this summertime , we ’ve assure even more . ”

The tenacious - full term prognosis for AFM patient is not have intercourse at this time . Treatment varies on a case - by - font basis and typically eye on strong-arm therapy to find strength in the affected limb(s ) and other muscle .

The Minnesota Department of Health are now looking into vulgar broker between the six children in Minnesota , all of whom are under 10 years old . They ask parents to keep an centre out for likely AFM symptoms in their tyke and to get them in for an urgent exam if any come along .
