U.K. also investigating cases of polio-like condition
Public health officials in the U.K. say they're also investigating an uptick in cases of acute flaccid myelitis, the mysterious, polio-like condition that has stumped health officials in the U.S. There have been 28 cases of AFM reported in England this year, most of which have cropped up since September. U.K. health officials say they typically only see a handful of cases of AFM each year. In the U.S., AFM cases have been higher on alternating years since an increase was first seen in 2014. So far this year, there have been a record 165 cases confirmed in the U.S., according to the CDC. Scientists still don't know what causes the condition.
