Diarrhea: If you had a viral intestinal infection stool tests would be negative and symptoms resolve within a week or so. If diarrhea lasts much longer stool is cultured for pathogens including bacteria, parasites and eggs. Avoid harsh roughage, drink adequate fluids and take kaopectate or Imodium temporarily. If symptoms persist much longer, see your physician or gastroenterologist for appropriate tests
