Eight children treated for possible rare neurological disorder

Jenna Hanchard reports.

SEATTLE -- Eight children from four Washington counties have received treatment at Seattle Children's for acute neurological illnesses, the state health department announced Friday.

“As part of our work to understand their symptoms, we are investigating the possibility of a condition known as acute flaccid myelitis (AFM),” the department said in a statement but added there are no confirmed cases of AFM.

Five of the children have been treated and released, but the other three remain hospitalized. Three children are from King County, two from Whatcom and Franklin counties, and one from Pierce County.

The children, whose ages ranged from three to 14, were admitted to the hospital between mid-September and Oct. 20. State officials stressed while there are similarities between the cases, the children have not received an official AFM diagnosis.

"It’s very unusual to have a cluster of these cases so close together, and I’m concerned we don’t have answers yet," said state epidemiologist Scott Lindquist.

AFM affects a person’s nervous system, specifically the spinal cord. AFM can result from a variety of causes, including viral infections, according to the CDC. Symptoms typically include sudden weakness in one or more arms or legs, loss of muscle ton, and decreased or absent reflexes.

All eight children exhibited a loss of strength or movement in one or more arms or legs.

The health department says many viruses and germs are linked to AFM, including common germs that can cause colds and sore throats, and respiratory infections. It can also be caused by poliovirus and non-polio enteroviruses, mosquito-borne viruses such as West Nile or Zika, and autoimmune conditions.

Seattle Children’s says parents should not be worried about bringing their children to the hospital.

“We are following our standard infection control protocols, including putting patients with symptoms of active respiratory infections in isolation, so they do not have contact with any other patients,” said Dr. Mark Del Beccaro, chief medical officer, in a statement.

The CDC will make the final determination regarding whether these are confirmed cases of AFM or not. There were two confirmed cases of AFM in Washington in 2014, but none last year. So far the CDC has seen 50 cases of AFM nationwide this year.

Heather Werdal said her son Hayden, 15, was one of the two children in Washington diagnosed with AFM two years ago.

"We watched the paralysis creep from his neck down and then he stopped breathing,” Wedal said. “His diaphragm quit working, so they had him intubated on a ventilator and within 10 days he was completely paralyzed to his toes."

Werdal said Hayden is still considered a quadriplegic two years later. He has some movement now, but is still considerably weak.

This new potential outbreak of AFM is scary for Werdal.

"It's terrifying because we think the numbers are higher than their saying,” Werdal said. “We think there are kids that are missed.”
