The principal of Buxton Center Elementary School in York County, Maine, Kim O’Donnell, sent a letter to parents notifying them of a pinworm outbreak on Wednesday, according to a Press Herald report.

O’Donnell encouraged parents of children with symptoms to contact their family physician. Pinworm is typically treated with either prescription or over-the-counter medication.

The school is disinfecting and cleaning surfaces and staff have been reminded to practice appropriate precautions, the letter said.
