A mysterious illness possibly linked to COVID-19 is affecting more children across the country. At least three children in the D.C. area are being treated for it right now as doctors nationwide search for answers. News4’s Doreen Gentzler explains the symptoms to look out for.
More than 20 pediatric patients are being treated for a mysterious illness linked to COVID-19 at Children's National Hospital in Washington, D.C., as doctors worldwide search for answers.
The hospital said Wednesday doctors are now treating 23 children for the rare but serious illness called multisystem inflammatory syndrome, or MIS-C. On May 12, there were just three patients with the illness at the hospital.
Virginia reported its first case of MIS-C on Tuesday in the Fairfax County area. In Maryland, there have been four cases of the illness, including a Baltimore County teenager who died.
Up to five children in New York may have died from MIS-C.
Symptoms are similar to a known issue called Kawasaki Disease, which could potentially damage the heart or blood vessels.
Dr. Roberta DeBiasi, the chief of infectious diseases at Children's National Hospital, is helping to treat the young patients.
"They tend to have no respiratory symptoms and are coming in with high fever, abdominal pain," she said in a previous interview with News4.

DeBiasi says the newly identified syndrome appears to be the result of a child's immune system's going into overdrive after a COVID-19 infection, even though some didn't know they had caught the virus.
"Your body does what it usually does with antibodies to clear the infection, but then this response is either too much or too long or dysregulated so you're accidentally inflaming all these other parts of the body," DeBiasi said.
Pediatric multi-system inflammatory syndrome usually develops weeks after a coronavirus infection. Symptoms may include fever, rashes, abdominal and chest pain, changes to skin color and rapid heart rate.
MIS-C has been reported in at least 19 states and Washington, D.C. New York Gov. Andrew Cuomo says six European countries have also seen cases.
As doctors search for clues to this condition, they're also searching for ways to treat it.
"We're not sure yet, internationally, if we should be targeting the virus or targeting the immune response," DeBiasi said, noting different treatments are being used. But knowledge of similar conditions like Kawasaki Disease can help guide treatment.
The new syndrome is rare and most kids will recover, doctors say. But it's important to know the signs, call your health care provider with concerns and visit the emergency room if needed.
Two of the patients in the D.C. area were improving thanks to drugs that target the body's immune response, DeBiasi said.
The emerging syndrome highlights that doctors and researchers are still learning about the effects of the new coronavirus.
"Emerging viruses make people uncomfortable. Not just the patients, but also physicians," DeBiasi said.
