The study, published Friday in the journal Pediatrics, said the most common symptoms for children hospitalized with Covid-19 were fatigue, shortness of breath, cough, headache, muscle and body aches and fever.MIS-C is a rare condition that affects children, often -- but not always -- after Covid-19 infection.
For those with MIS-C, the new study found that a higher proportion needed intensive care-level support while they were in the hospital than in children with severe Covid.
Randolph's earlier research has found that vaccination can help prevent MIS-C and serious illness in children.
The reassuring news, Randolph said, was that most of the kids hospitalized for MIS-C or Covid did not have symptoms lasting months after their initial infection.
However, the risk of severe illness and lingering complications among children hospitalized for Covid-19 is higher than the risk of severe side effects from the vaccine, which are very rare.
