text: <unk>  is defined as the passage of unformed or abnormally liquid stools at an increased frequency.<unk>  can be classified as acute or chronic. Acute<unk>  has a duration of less than 2 weeks and may be classified on the basis of etiology and presentation. On the basis of etiology, acute<unk>  may be classified into infectious and non-infectious subtypes. Subacute<unk>  is defined as a<unk>  lasting for two to four weeks. Although chronic<unk>  has multiple definitions, a current working definition is the production of loose stools for longer than 4 weeks. Frequent defecation with normal consistency is termed psuedo-diarrhea. There are 3 basic categories of chronic<unk> : watery, fatty (malabsorption), and inflammatory (with blood and pus). The diagnosis is based on duration of symptoms, signs, microscopic stool examination and culture, stool osmolarity, and in some rare instances colonoscopy. The treatment is mainly based on severity of symptoms, etiology and availability of medications. Prevention is based on proper maintaining the filtration systems at water plants, hand wash, and effectively use of alcohol-based hand sanitizers. Vaccination for some viruses, such as Rotavirus is a part of preventive measures.
