According to the Cambridge Fire Department, eight kids who were singing in a youth choir at a church close to Harvard University had “seizure-like” symptoms.
The eight kids had performed on stage on July 22 at St. Paul Parish in Cambridge, Massachusetts. They were part of the Choeur d’Enfants d’Île-de-France, a famous young choir that travels the world to play symphonies in churches.
However, witnesses told first responders that some of the children were ill during the performance because of a “stranger odour.”
The first to arrive on the scene were Cambridge firefighters, who treated the 11–13-year-old children for non-life-threatening conditions before taking them to hospitals. Before the concert, none of the youngsters had been experiencing any health issues.
