About 300 cases of children and adolescents with a rare and life-threatening syndrome associated with the new coronavirus have been identified in the United States in two studies.
The findings, published Monday in The New England Journal of Medicine, are following several reports of Covid-19 syndrome in France, Italy, Spain and Great Britain.
Multisistmian inflammatory syndrome in children (MIS-C) shares symptoms with Kawasaki disease, including fever, rashes, inflamed glands and, in severe cases, inflammation of the heart.
A consistent picture of the syndrome that occurs two or four weeks after coronavirus infection is emerging, Michael Levin, a professor of pediatrics and international child health at Imperial College London, said in an editorial accompanying the study.
The syndrome affects 2 out of 100,000 young people, defined as under the age of 21, out of 322 out of every 100,000 in that group who have Covid-19, he wrote.
While studies identified about 300 cases in the United States, Levin noted that more than a thousand cases have been reported worldwide. He added that there has been a relatively high proportion among black, Hispanic or South Asian people.
The first study, led by Boston Children's Hospital, found 186 cases of MIS-C in 26 U.S. states. Intensive care was required in four out of five and one in five mechanical ventilation was required. Four patients died.
The second study, which looked at patients in New York and was conducted by the state health department, found another 95 confirmed cases, four out of which four out of five needed to enter the intensive care unit. Two patients died.
It is not clear why MIS-C develops in some children and adolescents and not in others.
