Children tend to experience fewer COVID-19 symptoms or rarely experience life-threatening reactions than adults. To explore the possible causes for the same, a group of researchers from Yale University studied the immune responses in COVID-19 infected pediatric patients. The findings are published in the journal Immunity. Many children are asymptomatic, and only about one in 1,000 children can have a multi-system inflammatory response (MIS-C) four to six weeks after infection with SARS-CoV-2 .
This can lead to symptoms such as fever, abdominal pain with vomiting/diarrhea, rashes, and cardiovascular and neurological problems. In a comparative analysis, researchers tested blood from children with MIS-C, adults with severe COVID symptoms, as well as healthy children and adults.
