BLUE POINT - School officials say some Suffolk students who just returned from a school trip to Spain have contracted a bad stomach bug. 

Several students from Bayport-Blue Point High School are suffering from norovirus.

Officials say they may have gotten it from contaminated bottled water during their European trip.

According to officials, any student who may have the highly contagious bug should stay out of school until they're symptom free for 48 hours.
