There's been a spike in a rare polio-like disease that mostly affects children. State health officials say 14 cases have been reported in Colorado

6 Minnesota kids diagnosed with rare, polio-like disease

"The CDC will make the final determination on diagnoses and numbers are subject to change", the statement said. Other patients have it much worse.

The hospital is now working with the health department and Centers for Disease Control and Prevention to administer testing to confirm if the child does indeed have AFM.

It can cause a sudden onset of weakness or paralysis in the arms or legs, as well as loss of muscle tone and reflexes.

Acute flaccid myelitis is thought to happen after someone contracts a virus, like a poliovirus, West Nile virus, or adenovirus, the CDC says.

The illness causes a weakening of the nerves and resembles polio.

Since then, more than 350 cases of the illness have been reported in the US over a four-year period. A few require ventilators to breathe, NBC News reported.

There is no treatment other than managing each patient's symptoms.

"Scientifically, we don't understand why only some children will go on to develop AFM", Schleiss said.

There have been 38 confirmed cases of AFM in 16 states so far, KDKA-TV in Pittsburg reported.

The Colorado Department of Health says it has 14 confirmed cases this year, all of whom are children who needed hospitalization.

"The state health department has been monitoring this situation closely since early spring". It wasn't for two-year-old Maipele Burns, whose AFM attack caused her to lose all function in her right arm.

"Even with an increase in cases since 2014, AFM remains a very rare condition". "So, we've seen that there's an association between viruses, specifically enterovirus, in the past".

In previous years, cases of AFM in Colorado and elsewhere have been positive for a different enterovirus, EV-D68.

Health officials are "investigating six cases of suspected AFM" in the state as of Tuesday, Minnesota Department of Health spokesman Doug Schultz told Fox News. The CDC has not identified a germ that has been consistently found in every case of AFM, according to its website. The causes of cases are often not confirmed.

Fortunately, the disease is extremely rare with only 100 to 150 total cases per year - none of which have been reported in the Tri-State Area. The sixth case was announced Thursday, in Skagit County. According to the CDC, the largest number of cases, about 50, were reported in September 2014 before dropping to single digits in following months.
