So far, no one knows what it is. The school district says the air is clean and that children and employees should show up for school. But an increasing number of parents and teachers say they are afraid to go inside the building or to send their children there. Since the first day of school on Aug. 27, more than 15 teachers and seven custodians have suffered from severe headaches, chest pains, breathing problems and vomiting while inside Francis Scott Key Middle School. Last Wednesday, several teachers were taken by ambulance to a hospital. Others - under doctor's orders - have missed days of work. The article doesn't say just how many children are ill but I imagine it's alot since 15 teachers and 7 custodians are ill, taken away in ambulances, or ordered not to work by their doctors.
