The Wilson Daily printed an article about Norovirus that was written by a local physicaian, Dawn Brezina. In the article, she discusses Norovirus in general, the symptoms of Norovirus infection, and what you can do to prevent Norovirus from spreading:
Individuals who are sick or recovering should not fix food for other family members for at least two days after recovering from the illness. Spread within the family may be limited by washing linens, clothing, countertops and door knobs — and hand washing — frequently. It is estimated that nearly a third of Norovirus infections may be asymptomatic.
