This condition pops up every other year usually affecting the most children between August and November.
The Centers for Disease Control and Prevention issued a health alert on Friday that common respiratory viruses circulating this fall could lead to a rise in a rare, but serious condition that usually affects children called acute flaccid myelitis, AFM. This condition causes weakness that starts in the arms or legs and can lead to permanent paralysis or become life-threatening in severe cases.
The picture of AFM changed in 2020 when only 33 cases were confirmed. This is believed to be the effect of efforts aimed at mitigating COVID-like physical distancing and masking that led to fewer respiratory viral infections overall. As of early September 2022, 13 cases of AFM have been identified across five states.
