CINCINNATI -- At first, it seemed like 4-year-old Elijah Peacock had caught a cold. But his symptoms morphed into something much more serious.
"I never understood lethargia till I saw it in my son," Elijah's mom, Alex Voland, said. "We went to stand him up, and he collapsed."
The illness left Elijah with lower limb paralysis. Now he's in a wheelchair.
Doctors at Cincinnati Children's Hospital Medical Center said Elijah's symptoms match acute flaccid myelitis, though his case has not been confirmed as that condition.

According to the CDC, acute flaccid myelitis is "a rare but serious condition" that affects spinal cord gray matter and causes muscles and reflexes to weaken.
CDC officials said they started seeing an increase in cases in 2014. There have been 219 reports and 80 confirmed cases of the condition in the U.S. this year, as of Nov. 2. Those cases are spread across 25 states.
In Ohio, there have been five confirmed cases this year, compared to just two in 2017 and two in 2016. The 2017 cases were confirmed in Butler and Hamilton counties, and one of the 2016 confirmed cases was in Adams County.
Most of the patients with acute flaccid myelitis are children, according to the CDC.
Symptoms of acute flaccid myelitis include facial droop/weakness, difficulty moving eyes, drooping eyelids and difficulty swallowing or slurred speech, according to the CDC.
Doctors don't believe acute flaccid myelitis is contagious, according to Children's Hospital officials. However, the exact cause of the disease — likely a virus — has not been determined.
