Escherichia coli and Rotavirus are most commonly found in water and are known to cause moderate to severe diarrhea. 

It need not spread only through contaminated water even with bad hygiene practices like not washing hands after using the bathroom can also spread the germs leading to diarrhea.

Improper nutrition: 

Most children below the age of 5 are prone to diarrhea. But unfortunately every time they have an episode of diarrhea, it only makes their condition worse. In malnutritioned children diarrhea is a leading cause. 

Food Tolerance:

Food intolerance may come all sudden, but if you quickly catch food intolerance it can immediately cause acute or chronic diarrhea. Food intolerance is not related to food poisoning, as food intolerance is a condition where a certain ingredient of the food is not accepted by the body, but food poisoning is that which occurs when virus or bacteria infected food is intaken. 

Lactose intolerance is the best example of food intolerance. It means you do not have an enzyme that is needed to break down lactose, which is a type of sugar seen in milk, cheese, or any other dairy product.

IBD or inflammatory bowel disease, is an entirely different case of IBS. This condition occurs when the digestive tract is inflamed or irritated, and reduces the ability to absorb the nutrients from the food you intake. 

Certain medications:

The human digestive tract can have both good and bad bacteria. Good bacteria helps in maintaining the ph levels of the tract and also aids in digestion. But antibiotics cannot know the difference between bad and good bacteria leading to disrupt the digestion procedure leading to acute or chronic diarrhea.
