(CNN) This year, more than half of all US states have had confirmed or possible cases of acute flaccid myelitis, the polio-like illness that can cause paralysis and mostly affects children, according to an exclusive CNN analysis.

CNN reached out to health departments in every state; 48 states responded, plus the District of Columbia. Of those, 30 states said they had cases that were confirmed, suspected or being investigated -- including 15 states that said they had confirmed cases in 2018.

In total, CNN found 47 confirmed cases and 49 more that were suspected or being investigated, for a total of 96.

The US Centers for Disease Control and Prevention, which releases only confirmed numbers, says 16 states had 38 cases as of September 30. It does not identify the states.

CNN found that Colorado had 14 confirmed cases, more than any other state, followed by Texas with eight and Minnesota with six.
