Diarrhea is defined as the passage of loose stools three or more times in a 24-hour period in adults, and with twelve or more loose or watery stools for a breast-fed baby. It is generally classified as “acute watery”, “persistent” or “dysentery”. Acute watery diarrhea has an abrupt beginning and lasts less than 14 days. Persistent diarrhea lasts more than 14 days, which generally results in significant weight loss and nutritional problems . Diarrhea disease is one of the five leading causes of morbidity and mortality among children aged 0 and 5 years in the world, but the most hit areas are the low-income countries mostly in Asia and Africa. Global estimates show that deaths due to diarrhea have declined from 4.6 million in the 1980s and 3.3 million in the 1990s to 2.5 million by the year 2000 . In most instances diarrhea is preventable with some hygiene interventions that reduce contamination at household level .
