(WISH) – There are now 286 cases of possible and confirmed acute myelitis in the United States this year, according to the US Center for Disease Control and Prevention.
News 8 reported on AFM in October.
It includes 116 confirmed cases of the rare polio-like disease, also known as AFM, leading to sudden onset of paralysis. There are 10 more confirmed cases than the agency reported a week ago. An additional 170 possible cases of AFM are investigated.
More than 90% of the 440 patients with AFM since 2014 have been children younger than 4 years. Most children with confirmed cases experienced a viral disease with symptoms including fever and cough about three to ten days before paralysis, CDC said this month.
Patients with confirmed AFM are in 31 states, as CDC has now identified for the first time. There are 15 cases in Colorado, the state with the highest number, followed by Texas with 14 confirmed cases. Nineteen states have no confirmed cases and 12 states report only one confirmed case, according to the CDC.
It is not clear if there is more risk for AFM in states that have a larger number of cases or if these states are only better identifiable and reporting patients. Although CDC has encouraged doctors to report cases, there is no need to do so.
Most AFM patients became ill between August and October, and according to CDC, the number of diseases has reached each other since 2014.
Even with the increase in case, according to the CDC, "less than one in two in a million children in the United States will receive AFM each year."
