RALEIGH, N.C. — Officials with

N.C. State's Student Health Center

said they have provided care to 40 additional students Monday with vomiting and diarrhea, bringing the total to about 200 receiving care for similar symptoms since Feb. 9.

Norovirus

has been determined to be the cause, and symptoms last an average of one to two days.

On Monday, health officials said a N.C. State student has been diagnosed with the norovirus.

Treatment at Student Health has included medications to control vomiting, diarrhea, and fever, switching to clear liquid diet until symptoms improve and IV fluids for severe dehydration.

Officials said there has been no consistent connection to blame on food, residents at school and area or a social function with the disease.

To decrease your risk of infection, health officials suggest washing hands frequently, especially after use of the restroom, before eating, before preparing food and after being out in public. Students can receive medical care by calling Student Health Appointments at
