Most of the students sick with stomach flu at a Columbia County school have returned to classes today. Only 80 students were absent from Lewiston Elementary School in Evans today. School officials say 345 students, about half of the student population there, were absent on Friday. Most of the students had the norovirus. Some parents had checked their children out of school as a precautionary measure. The bug typically causes nausea, abdominal pain, vomiting and diarrhea, and lasts one or two days. It is highly contagious. School officials say they've shown students a video about proper handwashing, and have cleaned classrooms and multiuse areas.
