No special diet is required. A significant portion of patients have symptoms of lactose intolerance (cramping, bloating, diarrhea), and maintenance on a lactose-free diet for several months may be helpful. Acquired lactose intolerance occurs in as many as 20-40% of cases. [12]

Activity restrictions are not indicated. However, infected subjects who are at risk of spreading the infection should be isolated and treated.
