But not all who fall ill from an enterovirus will go on to develop the condition, experts say.
Earlier this month, six Minnesota children were diagnosed with the disease.
The rare, poorly understood, polio-like illness is thought to attack the body's nervous system - specifically, the spinal cord - and can cause paralysis.
At least two cases of a polio-like illness have been reported in Southeast Texas this year. Eight cases have been reported statewide.

The school was also anxious about a lack of heating and hot water on campus but they're no longer expecting to be impacted. The company will update its customers as soon as it is in a position to offer something new, said Stout.
"At this point there isn't evidence that would point to a single source of illness among these cases", Dr. Scott Lindquist, state infectious disease epidemiologist at the Department of Health, said.
Symptoms can include sudden arm or leg weakness, a loss of reflexes, facial droopiness or weakness, difficulty moving the eyes, drooping eyelids, difficulty swallowing, or slurred speech, the CDC says. "We're working closely with medical providers and public health agencies". Until then, doctors are treating the cases as if they are AFM. It is actively investigating AFM cases, and trying to unearth more information about the mysterious condition.
The CDC says it got information on 362 cases of the illness in the US from August 2014 through August 2018. A 2-year-old girl was recently diagnosed in the Chicago area, and UPMC Children's Hospital of Pittsburgh confirmed that three children are now being treated for AFM at their facility. Since that time, more than 360 new cases of AFM were reported. The condition was first described in 2014 and doctors assumed a virus was to blame, but they didn't know which one. On its website, the CDC explains that non-polio enteroviruses, which normally don't make people sick and if they do, it's often the common cold, can cause AFM.
However, 11 of the Colorado cases of AFM have tested positive for EV A71, a rare type of enterovirus not usually seen in the US but instead in Asia and other parts of the world, according to Dr. Rachel Herlihy, the Colorado state epidemiologist. However, it recommends practicing disease prevention measures, including staying up-to-date on vaccines and protecting yourself from mosquito bites. Three cases were reported in 2017, and one other case was reported in Washington since the beginning of 2018.
