The most common symptoms for children hospitalized with Covid-19 were fatigue, shortness of breath, cough, headache, muscle and body aches, and fever, the study published Friday in the journal Pediatrics said.
For children with MIS-C, “activity loss” — trouble performing normal activities — was the most common symptom in the study. Other severe symptoms include not being able to exercise or walk as usual, sleeping more than usual, and having trouble concentrating at school.
For people with MIS-C, the new study found that a higher proportion needed intensive care-level support when they were in hospital, compared to children with severe COVID. Children with asthma and obesity who had MIS-C were more likely to have symptoms after discharge.
Researchers in the new study surveyed 358 children receiving care in 25 pediatric hospitals between May 2020 and May 2021, before the rise in cases was caused by Delta or Omicron variants. It is not clear whether children with those variants will have different outcomes.
There was also a period of study before children were eligible to receive the COVID-19 vaccine.
A senior associate of critical care medicine at Boston Children’s Hospital and professor of anesthesia at Harvard Medical School, co-author Dr. Adrienne Randolph, co-author of the study, Dr. “Vaccine uptake for children is still not very high, but vaccines can stop it,” said Adrienne Randolph. , Randolph’s earlier research has found that vaccination can help prevent MIS-C and severe disease in children.
The reassuring news, Randolph said, was that most children hospitalized for MIS-C or COVID did not have symptoms until months after their initial infection.
He said that the cases of long-term Covid in hospitalized children were very less compared to older adults admitted in the hospital.
However, the risk of serious illness and prolonged complications in children hospitalized for COVID-19 outweighs the risk of serious side effects from the vaccine, which are very rare.
Randolph feels that parents are underestimating the risk they face when they fail to vaccinate their children.
“People will say ‘kids don’t get very sick, why worry about it,’ but the truth is that some children do get very sick. We have shown that even though survival is very high, some will have persistent symptoms, and some Will have serious illness. Hospitalization is also very disruptive. You don’t want your child to come into the hospital with severe pneumonia – period. It could affect their future lung function. MIS-C affects their heart could,” Randolph said. “Hopefully, this data will help people see how important vaccination is.”
