Development of a biomarker signature using grating-coupled fluorescence plasmonic microarray for diagnosis of MIS-C.

Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition that can develop 4-6 weeks after a school age child becomes infected by SARS-CoV-2. To date, in the United States more than 8,862 cases of MIS-C have been identified and 72 deaths have occurred. This syndrome typically affects children between the ages of 5-13; 57% are Hispanic/Latino/Black/non-Hispanic, 61% of patients are males and 100% have either tested positive for SARS-CoV-2 or had direct contact with someone with COVID-19.

Evaluation of measles IgM antibody detection assays during the 2018-2019 outbreak in New York State.

Although measles was eliminated in the United States in 2000, a severe outbreak occurred between October 2018 and September 2019. New York was especially hard hit. Serology played an integral role in determining immune status (IgG) and identifying, along with molecular analyses, acute measles infections (IgM).
