Children Can Suffer Severe Illness After COVID-19

COVID-19 surge could lead to more multisystem inflammatory syndrome cases in children
MIS-C in children

It was a few weeks before Christmas in 2020 when Alyssa Bendersky started worrying about her 6-year-old daughter, Paige. She had complained off and on about headaches and not feeling well for a few weeks, but she didn鈥檛 have a fever, and she didn鈥檛 test positive for COVID-19.

Then Paige became very ill. 鈥淪he had a fever, and it wasn鈥檛 going down,鈥 Bendersky said. 鈥淎nd she wasn鈥檛 eating or drinking.鈥 She had Paige checked out by doctors and even had her tested for COVID-19, but nothing was clearly wrong.

Then her fever spiked to 105 degrees, her blood pressure dropped, and she was taken by ambulance from Aurora to 脱衣直播. She was going into shock.

Paige was experiencing multisystem inflammatory syndrome in children (MIS-C), a rare, serious, sometimes fatal illness that may develop after a child has been infected with SARS-CoV-2, even if there was no diagnosis and even if there were no symptoms. The syndrome itself can be hard to diagnose before it becomes serious because its early symptoms are vague and common.

鈥淭hey didn鈥檛 know she had COVID, and then weeks later, Paige gets this very serious inflammatory response,鈥 Logan said. 鈥淎nd the only reason we know she had COVID-19 is because she had antibodies against the virus.鈥 

Paige was among a number of children treated for MIS-C at Rush鈥檚 pediatric intensive care unit last winter, weeks after COVID-19 cases in the Chicago area had risen sharply, according to , chief of pediatric infectious diseases at 脱衣直播.

More MIS-C cases likely

Now, COVID-19 is surging again, and this time, Rush is seeing more children with the virus, including more needing to be treated in the hospital, according to Logan.

"The vast majority of the children being hospitalized are under the age of 5, so ineligible for the vaccine, or are unvaccinated," Logan said, which underscores the need for those who are eligible for the vaccine and boosters to get them.

In the coming weeks, more children are likely to develop MIS-C, she said. 

鈥淲e know when there's a wave of COVID-19, we can expect to see a wave of MIS-C about four to six weeks later,鈥 Logan said in an .

MIS-C develops after acute COVID-19 infection, when the body launches an exaggerated inflammatory response that can affect blood vessels, the heart, lungs, gastrointestinal tract, kidneys 鈥 all of the major organs, she said.

At first, a child may experience vague symptoms, like fatigue or headaches, or symptoms commonly caused by other conditions, such as fever, rash, abdominal pain, diarrhea or vomiting.

鈥淢IS-C looks like a lot of other things,鈥 Logan said. But parents should pay attention if their child has symptoms, especially around four weeks after a confirmed or suspected case of COVID-19 or exposure to the virus. 鈥淚f your child has fever, body aches, diarrhea or headaches, complains of not feeling well or doesn鈥檛 look well, you really want to be on top of this and check with their doctor.鈥

Symptoms can change suddenly

What can be especially concerning about MIS-C is that these symptoms can quickly change to become quite serious.

鈥淪ome of these children are in shock when we see them,鈥 Logan said. 

That was the case with Paige, who was suffering from an infection and dehydration when the inflammation appeared to be affecting her heart. 

"Her heart rate was up, her blood pressure was low and her cardiac enzymes were elevated,鈥 an indication that her heart may not have been getting enough oxygen, pediatric cardiologist , told . 鈥淪he was very sick.鈥

After seven days of treatment at Rush University Children鈥檚 Hospital, six of them in intensive care, Paige鈥檚 symptoms subsided, and she went home.

While Paige continued to suffer occasional headaches for a few months, she, like most other MIS-C patients, recovered well, said Rush Copley Medical Center physician , who has been Paige鈥檚 pediatrician since her case of MIS-C.

鈥淣ow things look really good, and I wouldn鈥檛 know that she鈥檇 had it,鈥 Muscia said.

'You should get the vaccine'

After seeing her daughter suffer such a serious illness, Bendersky made sure her children received a COVID-19 vaccine as soon as they became eligible in October. 

鈥淚 don鈥檛 want a mom to go through what I went through,鈥 Bendersky. 鈥淚 remember just praying that she would make it." 

Like her mother, Paige, now 7, is an advocate for the COVID-19 vaccine, as well as for following precautions. 

鈥淵ou should get the vaccine because I ended up in the hospital and my heart almost stopped,鈥 she said, adding, 鈥淜eep your mask on and wash your hands.鈥
