Dr. Elizabeth Meade, chief of pediatrics at Swedish Pediatrics, says AFM is more common in kids and is especially associated with viruses.
There were two other suspected cases of AFM in the state earlier this year, according to Schultz. A few require ventilators to breathe, NBC News reported. Some people with AFM may be unable to urinate.
"The CDC has acknowledged that 362 cases of AFM have been reported since 2014, indicating an increasing infection rate", Klobuchar wrote in the letter.
Because of AFM's possible roots in polio, doctors and medical health professionals are urging parents to stay up-to-date on their children's vaccinations.
Outside of IL, there are now a few dozen cases of AFM in the United States.
The CDC recommends getting children vaccinated against the poliovirus, as well as protecting against bites from mosquitos (which carry the West Nile virus).
Health officials are warning parents to be on the lookout for symptoms.
However, 11 of the Colorado cases of AFM have tested positive for EV A71, a rare type of enterovirus not usually seen in the USA but instead in Asia and other parts of the world, according to Dr. Rachel Herlihy, the Colorado state epidemiologist. Numbness or tingling is rare in people with AFM, although some people have pain in their arms or legs.
While there is no cure, health experts say you should take preventative measures including washing your hands or coughing into your elbow.
