Mass Hysteria

During late January 1999 in a Bronx, New York City, intermediate school, 80 students and teachers fell suddenly and mysteriously ill, 40Â60 students became sick the next day, and 1,200 students were twice "evacuated." The complaints the victims reported included piercing headaches, chest pain, stomach pain, nausea, vomiting, disorientation, dizziness, fainting, and weakness. Said the principal: "Some felt nauseous, and their legs were weak. It was almost like they were hallucinating." Thirty-three students and three teachers were taken to hospitals, where oxygen was administered to some. An odor that suggested rotten eggs was reported.
