Polio-Like Disease Outbreak 2018: List of AFM Cases in States Across the United States

Heavy Breaking news

A mysterious disease that mimics polio called acute flaccid myelitis (AFM) has been reported in states across the United States. Here is a list, in alphabetical order by state, of cases recently reported.

The disease isn’t brand new this year. The CDC has reported cases dating back to 2014, and California reported some in 2012. Recently, 62 new cases have been confirmed in 22 states this year alone, USA Today reported.  Ninety percent of the cases involve children ages 18 or younger, with an average age of around 4 years old. The cause of most AFM cases isn’t known, but it’s sometimes linked to viruses. Symptoms may be similar to complications involving poliovirus, non-polio enteroviruses, adenoviruses, and West Nile, NBC reported. Other possibly linked viruses include EV-A71 and EV-D68, which are distant relatives of polio. The illness is more prominent in the fall during flu and respiratory season, Huffington Post reported.

If you or your child notice a sudden weakness or loss in muscle tone, especially in the arms or legs, see a doctor right away. Symptoms may also include a drooping face or eyelids, trouble with eye movement or swallowing, slurred speech, and in severe cases trouble breathing requiring a ventilator. There is one reported case of someone dying from AFM in 2017.

The CDC has not officially identified which states had confirmed cases. Here is what Heavy has gathered from local and national news reports.
