More than a dozen Virginia teens on a class trip to New York City were hospitalized Saturday after they fell ill during a matinee of the perennial Broadway hit, “The Phantom of the Opera.”

Paramedics were called to the Majestic Theater on W. 44th St. at about 3:30 p.m. as students began complaining of stomach pains. The teens appeared to be suffering from norovirus, a FDNY source said.

“They probably all ate at the same place,” the source said.

The students were taken to St. Luke’s-Roosevelt Hospital Center for evaluation.

The 2 p.m. show at the Majestic Theater — where Phantom’s been playing since 1988 — wasn’t interrupted as the sickened students were ushered out.

“A couple of people got sick, but the play went on,” a worker said.
