Parents of pupils at a Haverhill school are demanding that the school be closed after at least 10 teachers contracted a mysterious poison ivy-like rash.

The president of Haverhill Parents Shaping Our Schools said Monday that some teachers at the Hunking Middle School are reporting bronchial problems and they think something at the school is making them sick.

She tells The Eagle-Tribune that some of the affected teachers have been put on medications.

Superintendent James Scully says he is aware of only two teachers who have complained of rashes.

Scully maintains the building is safe and there is no reason to close the school. He thinks the number of ill teachers is being exaggerated. He says air-quality testing in the school has shown no problems.
