Looking ahead
The biggest question that still looms is what happens to these children, if anything, down the line.
“What was unique about this was this was a new disease we were all learning about together with no baseline,” Dr. Swami said. “None of us had ever seen this condition before.”
So far, the prognosis for the vast majority of children is good. “Most of these kids survive, most of them are doing well, and they almost all recover,” Dr. Serrano said. Labs tend to normalize by 6 weeks post discharge, if not much earlier, and not much cardiac involvement is showing up at later follow-ups. But not even a year has passed, so there’s plenty to learn. “We don’t know if there’s long-term risk. I would not be surprised if 20 years down the road we’re finding out things about this that we had no idea” about, Dr. Serrano said. “Everybody wants answers, and nobody has any, and the answers we have may end up being wrong. That’s how it goes when you’re dealing with something you’ve never seen.”
Research underway will ideally begin providing those answers soon. CHOP is a participating site in an NIH-NHLBI–sponsored study, called COVID MUSIC, that is tracking long-term outcomes for MIS-C at 30 centers across the United States and Canada for 5 years.

“That will really definitely be helpful in answering some of the questions about long-term outcomes,” Dr. Elias said. “We hope this is going to be a transient issue and that patients won’t have any long-term manifestations, but we don’t know that yet.”
Meanwhile, one benefit that has come out of the pandemic is strong collaboration, Dr. Bhumbra said.
“The biggest thing we’re all eagerly waiting and hoping for is standard guidelines on how best to follow-up on these kids, but I know that’s a ways away,” Dr. Bhumbra said. So for now, each institution is doing what it can to develop protocols that they feel best serve the patients’ needs, such as Riley’s new dedicated MIS-C clinic. “It takes a village to take care of these kids, and MIS-C has proven that having a clinic with all three specialties at one clinic is going to be great for the families.”
