New York City will test children for coronavirus antibodies after 38 developed a mysterious inflammatory illness
The illness, which de Blasio described as a rare multi-system “inflammatory syndrome,” has killed three children in the state, Gov. Andrew Cuomo announced on Saturday. One of them, a five-year-old, lived in the city, according to the mayor.
Among the 38 cases so far, nearly half tested positive for COVID-19, the disease caused by the coronavirus. Among those who tested negative, however, the vast majority had antibodies, de Blasio said at a Sunday press briefing.
While the accuracy of certain antibody tests has been called into question, they’re the only measure we have to detect infections. They look for antibodies that the body makes to fight off the coronavirus, which stick around in the blood for a while after symptoms pass.
They work best after two weeks since symptom onset, whereas diagnostic or “molecular” tests that use swabs and take respiratory samples find the virus earlier on, experts told Business Insider.
