ALBANY, N.Y. — A new study from the New York State Department of Health released Monday confirmed the Kawasaki-like multisystem inflammatory syndrome in children was related to widespread COVID-19 transmission, along with new information that officials said will help practitioners nationwide diagnose it in patients.
“This landmark study links COVID-19 and MIS-C and will help healthcare professionals throughout the country diagnose this condition in their patients,” said Commissioner of the New York State Department of Health Dr. Howard Zucker.
The study found that the peaks of MIS-C cases followed the peak of confirmed pediatric coronavirus cases by 31 days.
The study focused on 99 confirmed or suspected cases of MIS-C. Of the 99 patients, all under the age of 21, 36 had pre-existing conditions. Two patients died.
The most common pre-existing condition was obesity, according to the study.
Among 78 patients for whom race-related data was available, 40% were Black, 37% were White, 5% were Asian and 18% were considered other by the state.
Of the 99 patients, 85 identified their ethnicity, with 36% of those being Hispanic.
Study authors suggested that the higher number of cases of Black and Hispanic children may be a reflection of the "well-documented elevated incidence of COVID-19 infection among Black and Hispanic communities."
MIS-C has been associated with cardiac dysfunction, officials said.
The study was released Monday in the New England Journal of Medicine. The department said it collaborated with the University at Albany School of Public Health and the CDC to complete the study.
