Weegy: Diarrhea ? frequent runny or watery bowel movements (poop) ? is usually brought on by gastrointestinal (GI) infections caused by viruses, bacteria, [ or parasites.
The specific germs that cause diarrhea can vary among geographic regions depending on their level of sanitation, economic development, and hygiene. For example, developing countries with poor sanitation or where human waste is used as fertilizer often have outbreaks of diarrhea when intestinal bacteria or parasites contaminate crops or drinking water. ]
