Just a few dozen cases of MIS-A have been reported.

Sapna Bamrah Morris, clinical lead for the Health Care Systems and Worker Safety Task Force, part of the CDC's COVID-19 response, detailed 27 cases in a report the agency published last week.

Typically, severely ill COVID-19 patients tend to arrive at the hospital because they're having trouble breathing.

Many MIS-A patients report fevers, chest pain or other heart problems, diarrhea or other gastrointestinal issues — but not shortness of breath.

Instead, patients will test positive for COVID-19 antibodies, meaning they were infected two to six weeks previously, even if they never had symptoms.

"Just because someone doesn't present with respiratory symptoms as their primary manifestation does not mean that what they're experiencing isn't as a result of COVID-19," Morris said.

Underlying health conditions that raise the risk for COVID-19 complications, such as obesity and Type 2 diabetes, also tend to be more prevalent among members of racial and ethnic minority groups.

Over the summer, doctors in Florida started seeing surges in COVID-19 cases.

The most sensitive and reliable test for COVID-19, called a PCR test, wasn't always available, and it could take several days to return results.

What's more, while most severely ill COVID-19 patients tend to be over age 65 or to have multiple underlying health problems, these patients "were younger people that you would expect to not get sick," Abbo said.

The latter is taken from patients who have recovered from COVID-19 and have antibodies specifically targeted to the virus in their blood.

The thinking is that MIS-A patients already have COVID-19 antibodies, so adding more with convalescent plasma is unlikely to help.

The current theory for MIS-A patients is that "the infection, as far as we know, is gone," said Dr.

Even though MIS-A hadn't been identified at the time, Cassiere is convinced that such patients existed all along

"We were seeing patients who admitted to the ICU with organ failure," Cassiere said

They would test negative for COVID-19, he said, but test positive for COVID-19 antibodies, suggesting they'd been infected previously

"You look back, and they probably had this multi-system inflammatory syndrome," Cassiere said

"This needs to be in the forefront of every intensive care unit physician's mind who's seeing patients, especially when they have COVID-19 antibodies," Cassiere said

"There's not enough data for me to tell you what the long-term effects of this could be," Cassiere said
