DURHAM, N.C. — A class trip turned into a slight health problem for some Durham students.

It was not exactly the homecoming parents like Liz Moore expected on Friday.

"When I got here about 3:15, I was told by a police officer that I could not pick my child up," she said. "When I asked why, he said there was a virus and that the kids were quarantined. That was the only thing that he knew, so immediately, as a mother, I went into panic mode."

Luckily, there was no quarantine, just precautionary measures. On Wednesday, students from the Durham School of the Arts went to the Trinity Center in Carteret County on a field trip. Officials said a previous group of students visiting the center had gotten sick, along with the instructors.

On Friday morning, three of the Durham students got sick. Health officials believe a gastrointestinal virus may be to blame.

Health department workers said they are in touch with health workers in Carteret County to try and figure out exactly what they are dealing with. They said the symptoms only last a day.

Officials with Durham Public schools are not commenting.
