Nearly two dozen students at a Westchester County school were taken to the hospital with norovirus while on a trip to Washington, the school district said.
Twenty-two students at Isaac E. Young Middle School in New Rochelle came down with a stomach bug while on a trip to the nation's capital earlier this week, the district said.
All of the students were taken to a hospital afterward for evaluation, and 10 of the students were treated for dehydration.
School officials said that test results showed that the sickened students came down with norovirus.
It's not clear what caused the illnesses, but the students are expected to return home to New Rochelle Friday evening.
The school district said that parents had been kept informed "every step of the way" and that all of the students are safe.
